_______________General Desc ription
The MAX532 is a complete, dual, serial-input, 12-bit
multiplying digital-to-analog converter (MDAC) with out-
put amplifiers. No external user trims are required to
achieve full specified performance. The MAX532’s 3-
wire serial interface minimizes the number of package
pins, so it uses less board space than parallel-interface
parts. The interface is SPI, QSPI and Microwire
compatible. A serial output, DOUT, allows cascading
of two or more MAX532s and read-back of the data
written to the device.
The device’s serial interface minimizes digital-noise
feedthrough from its logic pins to its analog outputs.
Serial interfacing also simplifies opto-coupler-isolated
or transformer-isolated applications.
The MAX532 is specified with ±12V to ±15V power sup-
plies. All logic inputs are TTL and CMOS compatible. It
comes in space-saving 16-pin DIP and wide SO packages.
