AD7302BR-REEL7

Overview

The AD7302BR-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 swing capability via on-chip precision buffer amplifiers. The device utilizes a parallel microprocessor-compatible interface with double-buffered logic for simultaneous or individual DAC updates. Key electrical parameters include a maximum settling time of 2 μs, a typical current consumption of 2.8 mA at 5 V, and power-down current reduced to 1 μA max. 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 buffers
Parallel interface compatible with standard microprocessors and DSPs
Internal or external reference selection capability
Power-down mode reduces current consumption to less than 1 μA

Applications

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

Procurement Notes

Verify the specific package suffix associated with the REEL7 designation against the manufacturer's ordering guide to confirm the physical package type (e.g., TSSOP, SOIC). Confirm that the B version temperature range (-40°C to +105°C) meets the operational requirements of the target application environment.

Selection Notes

Select this component when a dual-channel, low-power DAC with rail-to-rail output is required for single-supply systems. Ensure the system interface supports parallel data loading with CS, WR, and A/B control signals. Consider the internal reference accuracy if an external precision reference is not utilized in the design.

Part Context

The AD7302 series includes variants such as the AD7302BN (DIP), AD7302BR (SOIC), and AD7302BRU (TSSOP). All share the same functional specifications but differ in package style. The REEL7 suffix typically indicates tape and reel packaging for automated assembly processes.
