FEATURES

DESCRIPTION

•

Micropower Operation: 160 µA @ 5 V

The DAC8571 is a small low-power, 16-bit voltage

•

Power-On Reset to Zero

interface. Its on-chip precision output amplifier allows

•

Single Supply: +2.7 V to +5.5 V

rail-to-rail

output

swing

and

settles

within

10

•

16-Bit Monotonic

microseconds. The DAC8571 architecture is 16-bit

•

Settling Time: 10 µs to

±0.003% FSR

monotonic, and factory trimming typically achieves

±4

•

mV absolute accuracy at all codes. The DAC8571

requires an external reference voltage to set its output

•

Supports Data Receive and Transmit

voltage range.

•

On-Chip Rail-to-Rail Output Buffer

•

Double-Buffered Input Register

The low power consumption and small size of this part

make it ideally suited to portable battery operated

•

Supports Synchronous Multichannel Update

equipment. The power consumption is typically 800 µW

•

Offset Error:

±1 mV max at 25°C

•

Full-Scale Error:

±3 mV max at 25°C

•

Small 8 Lead MSOP Package

are all supported up to 3.4 MHz serial clock speeds.
