Part Details:

18-Bit, 1 MSPS PulSAR 7.0 mW ADC in MSOP/QFN AD7982 FEATURES APPLICATION DIAGRAM EXAMPLE 18-bit resolution with no missing codes 2.5V TO 5V 2.5V Throughput: 1 MSPS Low power dissipation 7.0 mW at 1 MSPS REF VDD VIO 1.8V TO 5V 70 W at 10 kSPS IN+ SDI 3- OR 4-WIRE AD7982 SCK INL: ±1 LSB typical, ±2 LSB maximum INTERFACE ±10V, ±5V, .. IN­ SDO (SPI, CS Dynamic range: 99 dB GND CNV ADA4941 DAISY CHAIN) 100 True differential analog input range: ±V 3- REF 5106 0 V to VREF with VREF between 2.5 V to 5.0 V Figure 1. Allows use of any input range Easy to drive with the ADA4941 GENERAL DESCRIPTION No pipeline delay The AD7982 is an 18-bit, successive approximation, analog-to- Single-supply 2.5 V operation with 1.8 V/2.5 V/3 V/5 V logic digital converter (ADC) that operates from a single power supply, interface VDD. It contains a low power, high speed, 18-bit sampling ADC Serial interface SPI®-/QSPITM-/MICROWIRETM-/DSP-compatible and a versatile serial interface port. On the CNV rising edge, Ability to daisy-chain multiple ADCs and busy indicator the AD7982 samples the voltage difference between the IN+ 10-lead package: MSOP (MSOP-8 size) and 3 mm × 3 mm QFN and IN- pins. The voltages on these pins usually swing in (LFCSP), SOT-23 size opposite phases between 0 V and VREF. The reference voltage, APPLICATIONS REF, is applied externally and can be set independent of the supply voltage, VDD. Its power scales linearly with throughput.
