General Description

The MAX5541 serial-input, voltage-output, 16-bit monoto-

nic digital-to-analog converter (DAC) operates from a

single +5V supply. The DAC output is unbuffered, result-

ing in a low 0.3mA supply current and low 1LSB offset

error. The DAC output range is 0V to V

. The DAC

latch accepts a 16-bit serial word. A power-on reset

(POR) circuit clears the DAC output to 0V (unipolar

mode) when power is initially applied.

The 10MHz 3-wire serial interface is SPI™/QSPI™/

MICROWIRE™-compatible and interfaces directly with

optocouplers for applications requiring isolation. The

MAX5541 is available in an 8-pin SO package. For the

1LSB (max) INL version, refer to the MAX541 data sheet.
