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.

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.
