AD7302BRUZ

Overview

The AD7302BRUZ is a dual, 8-bit voltage output digital-to-analog converter (DAC) from Analog Devices Inc. Operating on a single +2.7 V to +5.5 V supply, it features on-chip precision output buffers that allow rail-to-rail voltage swing. The device utilizes a parallel microprocessor and DSP-compatible interface with high-speed registers and double-buffered logic. Data loads on the rising edge of CS or WR, while the A/B pin selects DAC A or B. It supports internal reference derived from VDD or external reference at REFIN. Both DACs update simultaneously via LDAC and clear via CLR. Power consumption is typically 15 mW at 5 V, reducing to under 3 μW in power-down mode.

Feature Summary

Dual 8-bit DACs with rail-to-rail output buffers
Parallel interface compatible with microprocessors and DSPs
Internal or external reference capability
Power-down mode consuming less than 1 μA

Applications

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

Procurement Notes

Verify the specific suffix BRUZ corresponds to the TSSOP-20 package and the B temperature grade (-40°C to +105°C). Confirm RoHS compliance status for the specific manufacturing lot. Ensure the source document matches the REV. 0 datasheet specifications for settling time and accuracy.

Selection Notes

Select this component when dual independent 8-bit outputs are required in a compact TSSOP-20 footprint. Choose the internal reference for simplified designs or an external reference for higher precision. Ensure the system operates within the 2.7 V to 5.5 V supply range and requires parallel data loading speeds.

Part Context

The AD7302 belongs to the AD730x series of low-power DACs. The BRUZ designation indicates the B version operating temperature range and the RU-20 Thin Shrink Small Outline package. It serves as a cost-effective solution for applications needing multiple analog outputs without serial interface overhead.
