General Description

The MP3274 is a complete 32-channel, 12-bit Data Acquisition Subsystem with 3-state output buffers for direct interfacing to 16-bit microprocessor buses.

Implemented using an advanced BiCMOS process, the converter combines a 32-channel passive overvoltage protected multiplexer instrumentation amp, a sample & hold, a SAR, a 12-bit decoded D/A, a comparator, a precision reference and the control logic to achieve an accurate, repeated conversion in less than 15µs, and a mux/instrumentation amp settling period of less than 10µs.

A unique input design provides input overvoltage protection to 50 V over the supply voltages.
