MAX531：+5V, Low-Power, Voltage-Output, Serial 12-Bit DACs

5V or +/-5V Supplies; See MAX5352 for Improved Single-Supply Operation

The MAX531/MAX538/MAX539 are low-power, voltage- output, 12-bit digital-to-analog converters (DACs) specified 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 packages. 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.
