General Description
The MAX541/MAX542 are serial-input, voltage-output,
16-bit digital-to-analog converters (DACs) that operate
from a single +5V supply. They provide 16-bit perfor-
mance (±1LSB INL and DNL) over temperature without
any adjustments. The DAC output is unbuffered, result-
ing in a low supply current of 0.3mA and a low offset
error of 1LSB.
The DAC output range is 0V to VREF. For bipolar opera-
tion, matched scaling resistors are provided in the
MAX542 for use with an external precision op amp
(such as the MAX400), generating a ±VREF output
swing. The MAX542 also includes Kelvin-sense con-
nections for the reference and analog ground pins to
reduce layout sensitivity.
A 16-bit serial word is used to load data into the DAC
latch. The 10MHz, 3-wire serial interface is compatible
with SPI/QSPI/MICROWIRE, and it also interfaces
directly with optocouplers for applications requiring isola-
tion. A power-on reset circuit clears the DAC output to 0V
(unipolar mode) when power is initially applied.
The MAX541 is available in 8-pin plastic DIP and SO
packages. The MAX542 is available in 14-pin plastic
DIP and SO packages.
