_______________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.
