3 Description

The 16-bit DAC81401 and 12-bit DAC61401

(DACx1401) devices are a pin-compatible family of

single-channel, buffered, high-voltage-output digitalto-

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.
