AD7303BR-REEL7

Overview

The AD7303BR-REEL7 is a dual, 8-bit voltage output digital-to-analog converter (DAC) from Analog Devices. It operates on a single +2.7 V to +5.5 V supply and features rail-to-rail output buffers with a typical settling time of 1.2 μs. The device utilizes a versatile 3-wire serial interface compatible with SPI, QSPI, Microwire, and DSP standards, supporting clock rates up to 30 MHz. Each DAC includes individual power-down capabilities, reducing current consumption to typically 80 nA in full power-down mode. The internal reference or external reference input allows flexible configuration for portable battery-powered applications.

Feature Summary

Dual 8-bit DACs with rail-to-rail output buffering
Single supply operation from +2.7 V to +5.5 V
3-wire serial interface compatible with SPI, QSPI, and Microwire
Individual DAC power-down with low current consumption

Applications

Portable battery powered instruments
Digital gain and offset adjustment
Programmable voltage and current sources
Programmable attenuators

Procurement Notes

Verify the package type associated with the 'R' suffix (SOIC-8) against specific design requirements. Confirm that the REEL7 designation indicates tape and reel packaging suitable for automated assembly processes. Ensure compatibility with the intended serial communication protocol speeds up to 30 MHz.

Selection Notes

Select this component when dual independent 8-bit outputs are required within an 8-pin footprint. Consider the internal reference capability if external precision references are unavailable. Verify that the load conditions remain within the specified sink/source current limits to maintain accuracy and stability.

Part Context

The AD7303 series includes variants such as the AD7303BN (DIP), AD7303BR (SOIC), and AD7303BRM (microSOIC). The BR variant specifically denotes the SOIC-8 package option. This family is designed for low-power, single-supply applications requiring precise analog control in compact systems.
