MP3274 Datasheet 12-bit Data ACquisition Subsystem

Manufacturer: Exar (now MaxLinear)

Overview: .. MP3274 Fault Protected 32 Channel, 12-Bit Data Acquisition.

General Description

The MP3274 is a plete 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 bines a 32-channel passive overvoltage protected multiplexer instrumentation amp, a sample & hold, a SAR, a 12-bit decoded D/A, a parator, 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.

Key Features

  • Complete 32-Channel 12-Bit A/D Converter with Sample & Hold, Reference, Clock and 3-State Outputs.
  • Fast Conversion, less than 15µS.
  • Microprocessor Bus Interface.
  • Parallel or Serial Data Output Modes.
  • 65 ns Bus Access Time.
  • Remote Analog Ground Sensing.
  • Overvoltage Protected Input (50 V over the Supply Voltages).
  • Precision Reference for Long Term Stability and Low Gain T. C.
  • Guaranteed Linearity Over Temperature.
