MAX5442ACUB+ Datasheet MAX5442AEUB+, MAX5442ACUB+, MAX5444AEUB+ | P1-P3

General Description

The MAX5441–MAX5444 are serial-input, voltage-out-

put, 16-bit digital-to-analog converters (DACs) in tiny

µMAX

packages, 50% smaller than comparable DACs

in 8-pin SOs. They operate from low +3V (MAX5443/

MAX5444) or +5V (MAX5441/MAX5442) single sup-

plies. They provide 16-bit performance (±2LSB INL and

±1LSB DNL) over temperature without any adjustments.

Unbuffered DAC outputs result in a low supply current

of 120µA and a low offset error of 2LSB.

The DAC output ranges from 0 to V

REF

. For bipolar

operation, matched scaling resistors are provided in

the MAX5442/MAX5444 for use with an external preci-

sion op amp (such as the MAX400), generating a

±V

REF

output swing.

A 16-bit serial word is used to load data into the DAC

latch. The 25MHz, 3-wire serial interface is compatible

with SPI/QSPI™/MICROWIRE, and can interface directly

with optocouplers for applications requiring isolation. A

power-on reset circuit clears the DAC output to code 0

(MAX5441/MAX5443) or code 32768 (MAX5442

/MAX5444) when power is initially applied.

A logic low on CLR asynchronously clears the DAC out-

put to code 0 (MAX5441/MAX5443) or code 32768

(MAX5442/MAX5444) independent of the serial interface.

The MAX5441/MAX5443 are available in 8-pin µMAX

packages. The MAX5442/MAX5444 are available in 10-

pin µMAX packages.
