_______________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
also be operated with ±5V supplies. The MAX515
draws only 140µA, and the MAX504 (with internal refer-
ence) draws only 260µA. The MAX515 comes in 8-pin
DIP and SO packages, while the MAX504 comes in 14-
pin DIP and SO packages. Both parts have been
trimmed for offset voltage, gain, and linearity, so no fur-
ther 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
well 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.
For a hardware and software compatible 12-bit
upgrade, refer to the MAX531/MAX538/MAX539 data
sheet.

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.
