AD8303ARZ-REEL

Overview

The AD8303ARZ-REEL is a dual, complete 12-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It integrates a laser-trimmed internal voltage reference and operates from a single +2.7 V to +5.5 V supply. The device features two voltage-output DACs with a full-scale range of 2.0475 V and a resolution of 0.5 mV per bit. Key electrical specifications include a typical power dissipation of 9.6 mW at +3 V, a shutdown current of less than 1 μA, and a settling time of 4 μs to ±0.1% of full scale. It utilizes a 3-wire serial interface compatible with SPI and DSP standards.

Feature Summary

Dual 12-bit DACs with integrated, laser-trimmed bandgap reference
Single +3 V operation with extended supply range of +2.7 V to +5.5 V
Low power consumption: 9.6 mW typical; <1 μA in shutdown mode
3-Wire Serial SPI Compatible Interface with double-buffered shift register

Applications

Portable Communications
Digitally Controlled Calibration
Servo Controls
PC Peripherals

Procurement Notes

Verify the obsolete status of this component before procurement planning. Confirm that the REEL suffix indicates tape-and-reel packaging suitable for automated assembly. Ensure compatibility with existing system power supplies within the +2.7 V to +5.5 V range. Check for available replacement components if long-term supply is required.

Selection Notes

Select this component for applications requiring low-voltage, low-power dual DAC functionality. The internal reference eliminates external precision reference requirements. Consider the SO-14 package constraints for thermal management. Verify that the 3 mA output sourcing capability meets load requirements. Ensure logic levels are compatible with the driving microcontroller or DSP.

Part Context

The AD8303 is part of Analog Devices' line of low-power digital-to-analog converters. It is designed for battery-operated systems where power efficiency is critical. The device replaces discrete resistor ladder and amplifier solutions, offering a compact alternative in a 14-lead SOIC package. It serves as a dual-channel variant within the broader AD830x family.
