1-CH 14-BIT SUCCESSIVE APPROXIMATION ADC SERIAL ACCESS PDSO10

Unipolar GULL WING DUAL Not Qualified Analog to Digital Converter 85C 5.8V 19mW 500ksps

The AD7946 is a 14-bit, charge redistribution, successive approximation, analog-to-digital converter (ADC),which operates from a single 5 V power supply, VDD. It contains a low power, high speed, 14-bit sampling ADC with no missing codes, an internal conversion clock, and a versatile serial interface port. The part also contains a low noise, wide bandwidth, short aperture delay track-and-hold circuit. On the CNV rising edge, it samples an analog input IN+ between 0 V to REF with respect to a ground sense IN-. The reference voltage, REF, is applied externally and can be set up to the supply voltage. Its power scales linearly with throughput. The SPI-compatible serial interface also features the ability, using the SDI input, to daisy-chain several Ad Cs on a single, 3-wire bus or it 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. The AD7946 is housed in a 10-lead MSOP or a 10-lead QFN1 (LFCSP) with operation specified from -40oC to +85oC. 1 The QFN package is in development.
