AD7302BRZ-REEL7

Overview

The AD7302BRZ-REEL7 is a dual, 8-bit voltage output digital-to-analog converter (DAC) from Analog Devices. It operates on a single supply ranging from +2.7 V to +5.5 V and features rail-to-rail output capability via on-chip precision buffers. The device utilizes a parallel microprocessor-compatible interface with double-buffered logic for simultaneous or individual DAC updates. Key electrical parameters include a typical settling time of 1.2 μs, a maximum power consumption of 3 mA at 3.3 V, and a power-down current of less than 1 μA. The component supports both internal reference derived from VDD/2 and external reference inputs.

Feature Summary

Dual 8-bit DAC architecture with rail-to-rail output swing
Parallel interface compatible with standard microprocessors and DSPs
Internal or external reference selection capability
Low power operation: <10 mW active, <3 μW in power-down mode

Applications

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

Procurement Notes

Verify the package type matches the 'R' suffix designation for SOIC-20 when sourcing this specific reel variant. Confirm that the B version temperature range (-40°C to +105°C) meets system requirements. Ensure ESD precautions are observed during handling as the device is sensitive to electrostatic discharge.

Selection Notes

Select the AD7302BRZ-REEL7 when a dual-channel, low-cost 8-bit DAC with parallel interface is required. Consider the internal reference option if an external precision reference is not available. Verify that the 1.2 μs settling time and 7.5 V/μs slew rate satisfy the bandwidth needs of the application. Check load driving capabilities against the 10 kΩ to VDD/GND specification.

Part Context

This part belongs to the AD7302 family of dual 8-bit DACs. The BRZ suffix indicates the B grade temperature range and SOIC package, while REEL7 denotes tape and reel packaging. It serves as a cost-effective solution for applications requiring two independent voltage outputs from a single IC footprint.
