LTC7800 Demo Board | 8 ≥ VIN ≥ 40V, VOUT = 3.3V @ 10A
Analog Devices Inc.
Demonstration circuit 2786A is a single output high voltage non-isolated synchronous step-down converter that drives an all N-channel MOSFET power stage. It features the LTC7800, a low quiescent current high frequency (programmable fixed frequency from 320kHz up to 2.25MHz) synchronous step-down DC/DC controller housed in a small 3mm x 4mm QFN package.
This DC2786A operates over an input voltage range from 8V to 40V, while the LTC7800 can operate up to 60V. This demo board produces a 3.3V output voltage with up to 10A output current, and is configured with a sense resistor for current sensing. A mode selector allows the DC2786A to operate in forced continuous operation, pulse-skipping or Burst Mode® operation during light loads.
The LTC7800 features two integrated 5V gate drivers with 20ns deadtime which is good for GaN transistors or logic-level MOSFETs to maximize efficiency. The EXTVCC pin permits the LTC7800 to be powered from the output of the switching regulator or other available source, reducing power dissipation and improving efficiency. Please refer to the LTC7800 data sheet for a complete description of the part operation and application information.

AD8319-EVALZ
Analog Devices Inc.
The AD8319 is a demodulating logarithmic amplifier, capable of accurately converting an RF input signal to a corresponding decibel-scaled output. It employs the progressive compression technique over a cascaded amplifier chain, each stage of which is equipped with a detector cell. The device can be used in either measurement or controller modes. The AD8319 maintains accurate log conformance for signals of 1 MHz to 8 GHz and provides useful operation to 10 GHz. The input dynamic range is typically 40 dB (re: 50 ?) with error less than ?1 dB. The AD8319 has 8 ns/10 ns response time (fall time/rise time) that enables RF burst detection to a pulse rate of beyond 50 MHz. The device provides unprecedented logarithmic intercept stability vs. ambient temperature conditions. A supply of 3.0 V to 5.5 V is required to power the device. Current consumption is typically 22 mA, and it decreases to 200 ?A when the device is disabled.?The AD8319 can be configured to provide a control voltage to a power amplifier or a measurement output from the VOUT pin. Because the output can be used for controller applications, special attention was paid to minimize wideband noise. In this mode, the setpoint control voltage is applied to the VSET pin.The feedback loop through an RF amplifier is closed via VOUT, the output of which regulates the amplifier?s output to a magnitude corresponding to VSET. The AD8319 provides 0 V to (VPOS ? 0.1 V) output capability at the VOUT pin, suitable for controller applications. As a measurement device, VOUT is externally connected to VSET to produce an output voltage, VOUT, that is a decreasing linear-in-dB function of the RF input signal amplitude.The logarithmic slope is ?22 mV/dB, determined by the VSET interface. The intercept is 15 dBm (re: 50 ?, CW input) using the INHI input. These parameters are very stable against supply and temperature variations.The AD8319 is fabricated on a SiGe bipolar IC process and is available in a 2 mm ? 3 mm, 8-lead LFCSP_VD for an operating temperature range of ?40?C to +85?C.ApplicationsRF transmitter PA setpoint controls and level monitoring Power monitoring in radiolink transmitters RSSI measurement in base stations, WLANs, WiMAX, and radars

ADAU1328BSTZ
Analog Devices Inc.
The ADAU1328 is a high performance, single-chip codec that provides two analog-to-digital converters (ADCs) with differential input and eight digital-to-analog converters (DACs) with single-ended output using the Analog Devices, Inc. patented multibit sigma-delta (Σ-Δ) architecture. An SPI port is included, allowing a microcontroller to adjust volume and many other parameters. The ADAU1328 operates from 3.3 V digital and analog supplies. The ADAU1328 is available in a 48-lead (single-ended output) LQFP. Other members of this family include a differential DAC output version.The ADAU1328 is designed for low EMI. This consideration is apparent in both the system and circuit design architectures. By using the on-board PLL to derive the master clock from the LR clock or from an external crystal, the ADAU1328 eliminates the need for a separate high frequency master clock and can also be used with a suppressed bit clock. The digital-to-analog and analog-to-digital converters are designed using the latest ADI continuous time architectures to further minimize EMI. By using 3.3 V supplies, power consumption is minimized, further reducing emissions.APPLICATIONS Home theater systems Set-top boxes Digital audio effects processors
