+5V, Low-Power, Voltage-Output, Serial 12-Bit DACs
_______________General Description
The MAX531/MAX538/MAX539 are low-power, voltageoutput, 12-bit digital-to-analog converters (DACs) specified for single +5V power-supply operation. The MAX531 c a n also be operated with ±5V supplies. The MAX538/MAX539 draw only 140µA, and the MAX531 ( w i t h 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 w e l l 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.

Note 1: The output may be shorted to VDD, VSS, or AGND if the package power dissipation limit is not exceeded.
Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
