AD7302BR-REEL

Overview

The AD7302 is a dual, 8-bit voltage output digital-to-analog converter (DAC) operating from a single +2.7 V to +5.5 V supply. It features on-chip precision output buffers that allow rail-to-rail operation with a typical settling time of 1.2 μs. The device utilizes a parallel microprocessor and DSP-compatible interface with double-buffered logic for simultaneous or individual DAC updates. Reference selection can be internal (derived from VDD) or external via the REFIN pin. Power consumption is typically 15 mW at 5 V, reducing to less than 1 μA in power-down mode.

Feature Summary

Dual 8-bit DACs with rail-to-rail voltage outputs
Parallel interface compatible with standard microprocessors and DSPs
Internal or external reference capability
Power-down mode reduces current consumption to <1 μA

Applications

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

Procurement Notes

Verify the package suffix against the ordering guide: 'N' denotes Plastic DIP, 'R' denotes Small Outline (SOIC), and 'RU' denotes Thin Shrink Small Outline (TSSOP). Confirm the temperature range matches the B version specification (-40 °C to +105 °C). Ensure the specific reel quantity aligns with manufacturing standards for the selected package type.

Selection Notes

Select the AD7302 when dual-channel 8-bit resolution with high-speed parallel interfacing is required. The internal buffer amplifiers support rail-to-rail swing, making it suitable for single-supply applications. Consider the power-down feature for battery-operated designs where standby current must be minimized below 1 μA.

Part Context

The AD7302 belongs to Analog Devices' family of low-power, single-supply data converters. It is designed for applications requiring precise analog control from digital systems. The component integrates both DAC channels and reference circuitry into a compact 20-lead package, simplifying board layout compared to discrete solutions.
