GENERAL DESCRIPTION

The AD7788/AD7789 are low power, low noise, analog front

ends for low frequency measurement applications. The AD7789

contains a low noise 24-bit ∑-∆ ADC with one differential input.

The AD7788 is a 16-bit version of the AD7789.

INTERFACE

3-wire serial

SPI®, QSPI™, MICROWIRE™, and DSP compatible

Schmitt trigger on SCLK

The device operates from an internal clock. Therefore, the user

does not have to supply a clock source to the device. The output

data rate is 16.6 Hz, which gives simultaneous 50 Hz/60 Hz

rejection.

APPLICATIONS

Smart transmitters

Battery applications

Portable instrumentation

Sensor measurement

Temperature measurement

Pressure measurement

Weigh scales

The part operates with a single power supply from 2.5 V to

5.25 V. When operating from a 3 V supply, the power dissipation

for the part is 225 µW maximum. The AD7788/AD7789 is

housed in a 10-lead MSOP.
