_______________General Description
The MAX503 is a low-power, 10-bit, voltage-output digitalto-analog converter (DAC) that uses single 5V or dual ±5V
supplies. This device has an internal voltage reference plus
an output buffer amplifier. Operating current is only 250µA
from a single 5V supply, making it ideal for portable and
battery-powered applications. In addition, the shrink smalloutline package (SSOP) measures only 0.1 square inches,
using less board area than an 8-pin DIP. 10-bit resolution is
achieved through laser trimming of the DAC, op amp, and
reference. No further adjustments are necessary.
Internal gain-setting resistors can be used to define a DAC
output voltage range of 0V to +2.048V, 0V to +4.096V, or
±2.048V. Four-quadrant multiplication is possible without
the use of external resistors or op amps. The parallel logic
inputs are double buffered and are compatible with 4-bit, 8bit, and 16-bit microprocessors. For a hardware and software compatible 12-bit upgrade, refer to the MAX530 data
sheet. For DACs with similar features but with a serial data
interface, refer to the MAX504/MAX515 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.
