Circuit Description
The ISL26132 (2-channel) and ISL26134 (4-channel) devices are
very low noise 24-bit delta-sigma ADCs that include a
programmable gain amplifier and an input multiplexer. The
ISL26132 offers an on-chip temperature measurement
capability.
The ISL26132, ISL26134 provide pin compatibility and output
data compatibility with the ADS1232/ADS1234, and offer the
same conversion rates of 10Sps and 80Sps.
All the features of the ISL26132, ISL26134 are pin-controllable,
while offset calibration, standby mode, and output conversion
data are accessible through a simple 2-wire interface.
The clock can be selected to come from an internal oscillator, an
external clock signal, or crystal (4.9152MHz typical).
