GENERAL DESCRIPTION

Seismic data acquisition systems

DVMs

The AD7693 is a 16-bit, successive approximation, analog-to-

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

VDD. It contains a low power, high speed, 16-bit sampling ADC

with no missing codes, an internal conversion clock, and a

versatile serial interface port. On the CNV rising edge, it

samples the voltage difference between the IN+ and IN− pins.

The voltages on these pins swing in opposite phase between 0 V

and REF. The reference voltage, REF, is applied externally and

can be set up to the supply voltage, VDD.

Instrumentation

Medical instruments

Its 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 VIO supply.

The AD7693 is housed in a 10-lead MSOP or a 10-lead QFN¹

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