AD8303JRU

Overview

The AD8303JRU is a dual, complete 12-bit digital-to-analog converter (DAC) designed for single +3 V operation. It integrates a laser-trimmed internal voltage reference and rail-to-rail output amplifiers. The device provides two independent voltage outputs with a full-scale range of 2.0475 V and a resolution of 0.5 mV per bit. It operates on a supply voltage between +2.7 V and +5.5 V, consuming approximately 9.6 mW at +3 V. The unit features a 3-wire serial interface compatible with DSP and SPI standards, allowing for efficient data transfer via SDI, CLK, and CS pins.

Feature Summary

Dual 12-bit DACs with integrated laser-trimmed bandgap reference
Single +3 V supply operation with extended range of +2.7 V to +5.5 V
3-Wire Serial Interface compatible with DSP and SPI protocols
Low power consumption: 9.6 mW typical at +3 V; <1 μA shutdown current

Applications

Portable communications equipment
Digitally controlled calibration systems
Servo control loops
PC peripherals requiring low-voltage DACs

Procurement Notes

Verify the 'JRU' suffix against official Analog Devices documentation to confirm package type and temperature grade specifications. Confirm RoHS compliance status through the manufacturer's current product status page. Ensure ESD handling precautions are observed during assembly due to the sensitivity of the CMOS input structures.

Selection Notes

Select this component for applications requiring dual-channel precision in a compact surface-mount package. The AD8303AR variant offers the same electrical characteristics in a standard SOIC-14 package. Consider the AD8300 if only a single channel is required. Verify that the load capacitance does not exceed 500 pF to maintain stability without external compensation.

Part Context

The AD8303 belongs to the AD830x family of low-power, single-supply DACs from Analog Devices. It utilizes CBCMOS technology to achieve high analog accuracy with low static power dissipation. The device is designated as obsolete in current catalogs, indicating it has been superseded by newer generations or discontinued production.
