The reference voltage, REF, is applied externally and can be set independent of the supply voltage, VDD. The device power scales linearly with throughput.The SPI-compatible serial interface also features the ability, using the SDI input, to daisy-chain several ADCs on a single, 3-wire bus and provides an optional busy indicator. It is compatible with 1.8 V, 2.5 V, 3 V, or 5 V logic, using the separate supply, VIO.For space constrained applications, the AD7981 is available in a 10-lead mini small outline package (MSOP) with operation speci-fied from ?55?C to +175?C and 10-lead ceramic flat package (FLATPACK) with operation specified from ?55?C to +210?C.

The AD5590 is a 16-channel input and 16-channel output analog I/O port with eight uncommitted amplifiers, operating from a single 4.5 V to 5.25 V supply. The AD5590 comprises 16 input channels multiplexed into a 1 MSPS, 12-bit successive approximation ADC with a sequencer to allow a preprogrammed selection of channels to be converted sequentially. The ADC contains a low noise, wide bandwidth track-and-hold amplifier that can handle input frequencies in excess of 1 MHz.The conversion process and data acquisition are controlled using ASYNC and the serial clock signal, allowing the device to easily interface with microprocessors or DSPs. The input signal is sampled on the falling edge of ASYNC and conversion is also initiated at this point. There are no pipeline delays associated with the ADC. By setting the relevant bits in the control register, the analog input range for the ADC can be selected to be a 0 V to VREFA input or a 0 V to 2 ? VREFA with either straight binary or twos complement output coding. The conversion time is determined by the ASCLK frequency because it is also used as the master clock to control the conversion.The DAC section of the AD5590 comprises sixteen 12-bit DACs divided into two groups of eight. Each group has an on-chip reference. The on-board references are off at power-up, allowing the use of external references. The internal references are enabled via a software write.The AD5590 incorporates a power-on reset circuit that ensures that the DAC outputs power up to 0 V and remain powered up at this level until a valid write takes place. The DAC contains a power-down feature that reduces the current consumption of the device and provides software-selectable output loads while in power-down mode for any or all DAC channels. The outputs of all DACs can be updated simultaneously using the LDAC function, with the added functionality of user-selectable DAC channels to simultaneously update. There is also an asynchronous CLR that updates all DACs to a user-programmable code: zero scale, midscale, or full scale.The AD5590 contains eight low noise, single-supply amplifiers. These amplifiers can be used for signal conditioning for the ADCs, DACs, or other independent circuitry, if required.APPLICATIONS Optical Line Cards (Monitoring and Control) Base Stations General Purpose Analog I/O Monitoring and control

The ADM1178 is an integrated hot swap controller and current sense amplifier that offers digital current and voltage monitoring via an on-chip 12-bit analog-to-digital converter (ADC), communicated through an I2C? interface.An internal current sense amplifier measures voltage across the sense resistor in the power path via the VCC pin and the SENSE pin.The ADM1178 limits the current through this resistor by control-ling the gate voltage (via the GATE pin) of an external N-channel FET in the power path. The voltage across the sense resistor (and therefore the inrush current) is kept below a preset maximum.The ADM1178 protects the external FET by limiting the time that the maximum current runs through it. This current limit period is set by the value of the capacitor attached to the TIMER pin. Additionally, the device provides protection from overcurrent events that may occur after the hot swap event is complete. In case of a short-circuit event, the current in the sense resistor exceeds an overcurrent trip threshold, and the FET is switched off immediately by pulling down the GATE pin.A 12-bit ADC can measure the current seen in the sense resistor, as well as the supply voltage on the VCC pin. An alert output can be set to trigger when the ADC current reading exceeds a programmed overcurrent limit threshold.An industry-standard I2C interface allows a controller to read current and voltage data from the ADC. Measurements can be initiated by an I2C command. Alternatively, the ADC can run continuously, and the user can read the latest conversion data whenever it is required. Up to four unique I2C addresses can be created, depending on how the ADR pin is connected.The ADM1178 is packaged in a 10-lead MSOP.ApplicationsPower monitoring/power budgeting Central office equipment Telecommunication and data communication equipment PCs/servers
