The ADIS16500 is a precision, miniature microelectromechanical system (MEMS) inertial measurement unit (IMU) that includes a triaxial gyroscope and a triaxial accelerometer. Each inertial sensor in the ADIS16500 combines with signal conditioning that optimizes dynamic performance. The factory calibration characterizes each sensor for sensitivity, bias, alignment, linear acceleration (gyroscope bias), and point of percussion (accelerometer location). As a result, each sensor has dynamic compensation formulas that provide accurate sensor measurements over a broad set of conditions.?The ADIS16500 provides a simplified, cost effective method for integrating accurate, multi-axis inertial sensing into industrial systems, especially when compared with the complexity and investment associated with discrete designs. All necessary motion testing and calibration are part of the production process at the factory, greatly reducing system integration time. Tight orthogonal alignment simplifies inertial frame alignment in navigation systems. The serial peripheral interface (SPI) and register structure provide a simple interface for data collection and configuration control.?The ADIS16500 is available in a 100-ball, ball grid array (BGA) package that is approximately 15 mm ? 15 mm ? 5 mm.Applications?

The ADL5206 is a wide bandwidth, variable gain amplifier (VGA) with digital control (also known as a digital gain amplifier (DGA)) that provides precise gain control, high output third-order intercept (OIP3), and low noise figure over the entire gain range. The excellent OIP3 performance of 39.4 dBm (at 300MHz, 5 V supply, and maximum gain) makes the ADL5206 an excellent gain control device for a variety of receiver applications. For wide input dynamic range applications, the ADL5206 provides a broad 2 dB to 32 dB gain range with a 1 dB step size. The gain is adjustable through multiple gain control and interface options: parallel, serial peripheral interface (SPI), or gain step-up and step-down controls. The ADL5206 can be powered up independently by applying the appropriate logic level to the PWUP pin. The quiescent current of the ADL5206 is typically 112 mA with a 5 V supply. When disabled, the ADL5206 consumes only 8 mA and offers excellent input to output isolation. The gain setting is preserved when the device is disabled. Fabricated on the Analog Devices, Inc., high speed, silicon germanium (SiGe), bipolar complementary metal-oxide semiconductor (BiCMOS) process, the ADL5206 provides precise gain adjustment capabilities with good distortion performance. The ADL5206 amplifier comes in a compact, thermally enhanced, 4 mm ? 4 mm, 20-lead LFCSP and operates over the temperature range of ?40?C to +85?C. Note that throughout the data sheet, multifunction pins, such as CS/GS1/D3, are referred to by the entire pin name or by a single function of the pin.

The ADL5303 is a monolithic logarithmic detector optimized for the measurement of low frequency signal power in fiberoptic systems and offers a large dynamic range in a versatile andeasily used form. Wide measurement range and accuracy are achieved using proprietary design and precise laser trimming.The ADL5303 requires only a single positive supply, VPS, of 5 V. When using low supply voltages, the log slope can be altered tofit the available span. Low quiescent current and chip disablefacilitate use in battery-operated applications.The input current, IPD, flows in the collector of an optimally scaled NPN transistor, connected in a feedback path around alow offset JFET amplifier. The current summing input nodeoperates at a constant voltage, independent of current, with a default value of 0.5 V; this may be adjusted over a wide range. An adaptive biasing scheme is provided for reducing photo-diode dark current at very low light input levels. The VPDB pin applies approximately 0.1 V reverse bias across the photodiode for IPD = 100 pA, rising linearly to 2.0 V of reverse bias at IPD = 10 mA to improve response time at higher power levels. The input pin INPT is flanked by the VSUM guard pins that track the voltage at the summing node. Connecting the exposed pad of the device to the VSUM pins provides a continuous guard to minimize leakage into the INPT pin.The default value of the logarithmic slope at the VLOG output is set by an internal 5 k? resistor. Logarithmic slope can belowered with an external shunt resistor or increased using the buffer and a pair of external feedback resistors. The addition of a capacitor at the VLOG pin provides a simple low-pass filter.The intermediate voltage, VLOG, is buffered in an output stage that can swing to within about 100 mV of ground and the positive supply, VPS, and provides a peak current drive capacity of ?20 mA. An on-board 2 V reference is provided to facilitate the repositioning of the intercept. The incremental bandwidth of a translinear logarithmic amplifier inherently diminishes for small input currents. At IPD =1 nA, the bandwidth of the ADL5303 is approximately 2 kHz increasing in proportion to IPD up to a maximum value of 10 MHz.APPLICATIONS High accuracy optical power measurement Wide range baseband log compression Versatile detector for APC loops

The ADL5304 is a high speed logarithmic converter with fast response and low noise over a 200 dB (1 pA to 10 mA) measurement range. The ADL5304 provides a nominal logarithmic slope of 10 mV/dB (200 mV/decade); other values are easily configured. Logarithmic intercept can be programmed over a wide range with the internal 100 nA current source or externally for log ratio applications.The default intercept value of 3.162 fA places the midpoint of the measurement range of 100 nA at VLOG = 1.5 V.A single positive supply of 5 V is all that is required for operation over a specified 1 pA to 3 mA input range. Dual-supply operation extends the specified input current range to 10 mA.The ADL5304 accepts two current inputs to the logarithmic argument. The numerator input, INUM, flows in the collector of an NPN transistor, connected in a feedback path around a low offset JFET amplifier. The denominator current, IDEN, is treated in the same way, which allows for log ratio operation. The input summing nodes (INUM and IDEN) operate at a constant default voltage of 1.5 V. The VSM1 to VSM4 pins flank the INUM and IDEN inputs to provide a guard voltage to minimize leakage currents.Adaptive photodiode biasing is provided for optical measurements. A monitor current 1.1 times INUM is output at the IMON pin, and an external resistor, RMNTR, at 10 times the photodiode series resistance (RS) applies a voltage across the photodiode that 1st order keeps the internal PD junction at 0 V to minimize dark current.The VLOG output is buffered and can be rescaled through internal gain setting resistors. The internal ILOG varies from ?400 ?A to +400 ?A as INUM changes over 10 decades from 1 pA to 10 mA. This corresponds to 0.5 V to 2.5 V at the VLOG pin in the default configuration shown in Figure 1.Accurate 1.5 V (Pin 1P5V) and 2.0 V (Pin 2VLT) reference outputs allow precise repositioning of the intercept using external resistors.The ADL5304 is available in a 32-lead, 5 mm ? 5 mm LFCSP and specified for operation from ?40?C to +85?C.Applications High accuracy optical power measurement Wide range baseband log compression Versatile detector for high speed APC loops

The ADL5315 is a wide input current range precision high-side current mirror featuring a stable and user-adjustable input voltage. It is optimized for use with PIN photodiodes, but its flexibility and wide operating range make it suitable for a broad array of additional applications. The part provides a compact solution for the common and often challenging problem of interfacing an optical power monitoring device (such as a log amp) to the cathode-side of a PIN photodiode. The ADL5315 mirrors the current at the cathode at a 1:1 ratio over a six-decade range, producing an output exactly proportional to the reference current monitored. Competing optical current monitors have much higher mirror ratios over narrower dynamic ranges, rendering proportional outputs at very low input currents impossible, while discrete solutions are more tedious to implement and may require significantly more board space.
