Overview
The AD7302BRUZ-REEL7 is a dual, 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices Inc. It operates on a single +2.7 V to +5.5 V supply and features rail-to-rail output swing 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. It supports both internal (VDD/2) and external reference inputs.
Feature Summary
- Dual 8-bit DACs in a single 20-lead TSSOP package
- Rail-to-rail output swing with 1.2 μs typical settling time
- Parallel interface with double-buffered registers
- Internal or external reference selection capability
Applications
- Portable battery-powered instruments
- Digital gain and offset adjustment circuits
- Programmable voltage and current sources
- Programmable attenuators
Procurement Notes
Verify the component matches the specific B version temperature range (-40 °C to +105 °C). Confirm the package type is TSSOP-20 as indicated by the RU suffix. Ensure the REEL7 designation corresponds to the required tape and reel quantity for manufacturing integration.
Selection Notes
Select this component when dual low-power 8-bit DACs are required in a compact surface-mount package. It is suitable for applications needing rail-to-rail output swings from a single supply. Consider the parallel interface requirements and ensure the system can accommodate the necessary control signals (CS, WR, LDAC, CLR).
Part Context
The AD7302 is part of Analog Devices' family of low-power, single-supply DACs. The BRU variant specifically denotes the industrial temperature grade and the Thin Shrink Small Outline Package. The REEL7 suffix indicates it is supplied in a standard tape and reel format for automated assembly processes.
Replacement Considerations
Direct pin-for-pin replacements within the same package and specification range should be verified against official Analog Devices cross-reference documentation. Ensure any substitute maintains the 2.7 V to 5.5 V operating voltage and parallel interface compatibility.
