ADA4841-x
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.
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 QFN
1
(LFCSP) with operation specified from 40°C to +85°C.
