General Description
The MAX5322 dual, 12-bit, serial-interface, digital-to-analog converter (DAC) provides bipolar ±5V to ±10V outputs from ±12V to ±15V analog power-supply voltages, or unipolar 5V to 10V outputs from a single 12V to 15V analog power-supply voltage.
The device features a fast 10MHz SPI™-/QSPI™-/MICROWIRE™-compatible serial interface that operates with 3V or 5V logic. Additional features include a serial data output (DOUT) for daisy chaining and read-back functions. The MAX5322 requires external reference voltages of 2V to 5.25V and is available in a 28-pin SSOP package that operates over the extended (-40°C to +85°C) temperature range.
