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
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.

In single-supply operation, INL and GE calculated from Code 3 to Code 1023.
Guaranteed by design.
Tested at IOUT = 100µA. The reference can typically source up to 5mA (see Typical Operating Characteristics).
The timing characteristics limits for the MAX515 are guaranteed by design.
