_______________General Description
The MAX531/MAX538/MAX539 are low-power, voltage-
output, 12-bit digital-to-analog converters (DACs) speci-
fied for single +5V power-supply operation. The MAX531
can also be operated with ±5V supplies. The
MAX538/MAX539 draw only 140µA, and the MAX531
(with internal reference) draws only 260µA. The
MAX538/MAX539 come in 8-pin DIP and SO packages,
while the MAX531 comes in 14-pin DIP and SO pack-
ages. All parts have been trimmed for offset voltage,
gain, and linearity, so no further adjustment is necessary.
The MAX538’s buffer is fixed at a gain of +1 and the
MAX539’s buffer at a gain of +2. The MAX531’s internal
op amp may be configured for a gain of +1 or +2, as
well as for unipolar or bipolar output voltages. The
MAX531 can also be used as a four-quadrant multiplier
without external resistors or op amps.
For parallel data inputs, see the MAX530 data sheet.
