GENERAL DESCRIPTION

The MP3275 is a complete 16-channel, 12-bit Data Acquisition Subsystem with serial data port. Implemented using an advanced BiCMOS process, the converter combines a 16-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 conversion in less than 15μs, and a mux/instrumentation amp settling period of less than 10μs.
