♦ Buffered Voltage Output
♦ Internal 2.048V Voltage Reference
The MAX503 is a low-power, 10-bit, voltage-output digital-
to-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 small-
outline 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.
♦ Operates from Single 5V or Dual ±5V Supplies
♦ Low Power Consumption:
250µA Operating Current
40µA Shutdown-Mode Current
♦ SSOP Package Saves Space
♦ Relative Accuracy: ±1 2 LSB Max Over

Temperature
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, 8-
bit, and 16-bit microprocessors. For a hardware and soft-
ware 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.
♦ Guaranteed Monotonic Over Temperature
♦ 4-Quadrant Multiplication with No External
Components
♦ Power-On Reset
♦ Double-Buffered Parallel Logic Inputs
