MAX5322 Datasheet PDF - Maxim Integrated

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 MAX5322 features excellent linearity with both integral nonlinearity (INL) and differential nonlinearity (DNL) guaranteed to ±1 LSB (max). The device also features a fast 10µs to 0.5 LSB settling time, and a hardware-shutdown feature that reduces current consumption to 2.8µA. The output goes to midscale at power-up in bipolar mode (0V), and to zero scale at power-up in unipolar mode (0V). A clear input (active-low CLR) asynchronously clears the DAC register and sets the outputs to 0V. The outputs can be asynchronously updated with the load DAC (active-low LDAC) input.

●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.
