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
2.5‑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.
