5V, Low-Power, Voltage-Output, Serial 10-Bit DACs
_______________General Description
The MAX504/MAX515 are low-power, voltage-output, 10-bit digital-to-analog converters (DACs) specified for single +5V power-supply operation. The MAX504 can a l s o be operated with ±5V supplies. The MAX515 draws only 140µA, and the MAX504 (with internal reference) draws only 260µA. The MAX515 comes in 8-pin DIP and SO packages, while the MAX504 comes in 14p i n DIP and SO packages. Both parts have been trimmed for offset voltage, gain, and linearity, so no further adjustment is necessary. The MAX515's buffer is fixed at a gain of 2. The MAX504'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 MAX504 can also be used as a four-quadrant multiplier without external resistors or op amps. For parallel data inputs, see the MAX503 data sheet. F o r a hardware and software compatible 12-bit upgrade, refer to the MAX531/MAX538/MAX539 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.
