T8532 Description
The T8532 block diagram is shown in Figure 2. Each of its eight channels consists of an antialias filter, sigma-delta
A/D and D/A converters, reconstruction and smoothing filters, termination impedance synthesis, and selectable
gain. The digital oversampled data is multiplexed onto a serial data port designed to interface with the T8531A
Another serial interface accepts control data from the T8531A for activating the various gain settings, self-test, and
powerdown modes. This chip also contains a precision voltage reference.
