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, ∑-Δ ADC with one differential
input. The AD7788 is a 16-bit version of the AD7789.
The devices operate from an internal clock. Therefore, the
user does not have to supply a clock source to the devices.
The output data rate is 16.6 Hz, which gives simultaneous
50 Hz/60 Hz rejection.
The parts operate with a single power supply from 2.5 V to
5.25 V. When operating from a 3 V supply, the power dissi-
pation for the part is 225 μW maximum. The AD7788/AD7789
are available in a 10-lead MSOP.
