GENERAL DESCRIPTION

Easy to drive with the ADA4941

No pipeline delay

Single-supply 2.5 V operation with 1.8 V/2.5 V/3 V/5 V logic

interface

Serial interface SPI®-/QSPI™-/MICROWIRE™-/DSP-compatible

Ability to daisy-chain multiple ADCs and busy indicator

10-lead package: MSOP (MSOP-8 size) and 3 mm × 3 mm QFN

(LFCSP), SOT-23 size

The AD7982 is an 18-bit, successive approximation, analog-to-

digital converter (ADC) that operates from a single power supply,

VDD. It contains a low power, high speed, 18-bit sampling ADC

and a versatile serial interface port. On the CNV rising edge,

the AD7982 samples the voltage difference between the IN+

and IN− pins. e voltages on these pins usually swing in

opposite phases between 0 V and V_REF. The reference voltage,

REF, is applied externally and can be set independent of the

supply voltage, VDD. Its power scales linearly with throughput.

APPLICATIONS

Battery-powered equipment

Data acquisition systems

Medical instruments

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, and 5 V logic, using the separate VIO supply.

Seismic data acquisition systems

The AD7982 is available in a 10-lead MSOP or a 10-lead QFN

(LFCSP) with operation specified from −40°C to +85°C.
