MAX503EAG Datasheet MAX503CWG+T, MAX503CNG, MAX503CAG | P1-P3

_______________General Description

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.

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.

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.
