Description

The MAX5312 12-bit, serial-interface, digital-to-analog converter (DAC) provides bipolar ±5V to ±10V outputs from ±12V to ±15V power-supply voltages, or a unipolar 5V to 10V output from a single 12V to 15V power-supply voltage.

The MAX5312 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 3.5µA. 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 output to 0V. The output can be asynchronously updated with the load DAC (active-low LDAC) input.

The device features a 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 MAX5312 requires a 2V to 5.25V external reference voltage and is available in a 16-pin SSOP package that operates over the extended -40°C to +85°C temperature range.
