AD7305BR-REEL7

Overview

The AD7305BR-REEL7 is a quad, 8-bit digital-to-analog converter (DAC) from Analog Devices. It features a fast parallel interface and operates from single +3 V to +5 V or ±5 V supplies. The device includes internal precision buffers with rail-to-rail output swing, allowing the full-scale voltage to match the supply rails or any intermediate reference value. Key electrical parameters include an 8-bit resolution, 1 MS/s sampling rate, and a settling time of 1 µs to ±0.1%. It consumes less than 9 mW at 3 V and supports an external reference input range spanning from VSS to VDD.

Feature Summary

Quad 8-bit DAC architecture with rail-to-rail buffered outputs
Fast parallel data interface with standard address decode
Operates on single (+3 V to +5 V) or dual (±5 V) supplies
Internal power-on reset ensures zero-scale output at turn-on

Applications

Automotive output span voltage control
Instrumentation and digitally controlled calibration systems
Pin-compatible replacement for AD7226 when VDD < 5.5 V

Procurement Notes

Verify the specific package variant against the datasheet, as the AD7305 series is available in 20-lead SOIC and TSSOP packages. Confirm that the design utilizes a parallel interface, as the serial AD7304 is functionally distinct despite shared specifications. Ensure the external reference voltage remains within the VSS to VDD operating range to maintain specified linearity.

Selection Notes

Select this component for applications requiring four independent voltage outputs with high-speed parallel loading. It is suitable for designs needing rail-to-rail output capability without external amplifiers. Verify that the system logic levels support the required data setup and hold times for the parallel interface. Consider the thermal resistance of the chosen package if operating near maximum power dissipation limits.

Part Context

The AD7305 is part of the AD7304/AD7305 family, distinguished by its parallel interface compared to the SPI-compatible AD7304. Both devices share identical analog performance characteristics, including R-2R ladder architecture and shutdown features. The AD7305 is designed to be pin-compatible with industry-standard parts like the AD7226 under specific voltage conditions, facilitating direct upgrades in existing hardware designs.
