The 16-bit DAC81401 and 12-bit DAC61401 (DACx1401) devices are a pin-compatible family of single-channel, buffered, high-voltage-output digital-to-analog converters (DACs) with an integrated 2.5V internal reference. These devices are specified monotonic and provide an exceptional linearity of less than 1LSB (maximum).
The DACx1401 offer bipolar output voltages of ±20V, ±10V, ±5V, and full-scale unipolar output voltages of 40V, 10V, and 5V. The DAC output range is programmable.
The DACx1401 incorporate a power-on-reset (POR) circuit that powers up the DAC output and keeps the devices in power-down mode until the outputs enable.
Communication to the devices is done through a high-speed, 4-wire serial interface compatible with industry-standard microprocessors and microcontrollers supporting 1.7V to 5.5V operation.
The DACx1401 are characterized for operation over the temperature range of –55°C to +125°C, and are available in a small 16-pin QFN and 20-pin TSSOP package.
