GENERAL DESCRIPTION
The AD7988-1/AD7988-5 are 16-bit, successive approximation,
analog-to-digital converters (ADC) that operate from a single
power supply, VDD. The AD7988-1 offers a 100 kSPS throughput,
and the AD7988-5 offers a 500 kSPS throughput. They are low
power, 16-bit sampling ADCs with a versatile serial interface
port. On the CNV rising edge, they sample an analog input,
IN+, between 0 V to VREF with respect to a ground sense, IN.
The reference voltage, REF, is applied externally and can be set
independent of the supply voltage, VDD.
The SPI-compatible serial interface also features the ability to
daisy-chain several ADCs on a single 3-wire bus using the SDI
input. It is compatible with 1.8 V, 2.5 V, 3 V, or 5 V logic using
the separate supply, VIO.
The AD7988-1/AD7988-5 generics are housed in a 10-lead
MSOP or a 10-lead LFCSP (QFN) with operation specified
from 40°C to +125°C.
