GENERAL DESCRIPTION

The AD7984 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 AD7984 samples the voltage difference between

the IN+ and IN− pins. The 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.

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

Ability to daisy-chain multiple ADCs and busy indicator

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

(LFCSP), SOT-23 size

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 AD7984 is available in a 10-lead MSOP or a 10-lead QFN

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