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