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.
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.
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.
