Single-channel 16-bit high-voltage-output DAC with precision internal reference

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.
