Overview
The AD5791SRU-EP is a single-channel, 20-bit, unbuffered voltage-output digital-to-analog converter (DAC) from Analog Devices. It operates on a bipolar supply up to ±16.5 V and features 1 ppm resolution with ±1 LSB INL. The device includes a power-on reset circuit ensuring the output powers up to 0 V and maintains a known impedance state until a valid write occurs. It supports a 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards at clock rates up to 35 MHz.
Feature Summary
- 20-bit resolution with 1 ppm INL and ±1 LSB DNL
- Military temperature range (-55°C to +125°C)
- Low noise spectral density of 7.5 nV/√Hz
- Enhanced Product (EP) features for defense/aerospace applications
Applications
- Medical instrumentation
- Test and measurement
- Industrial control
- High-end scientific and aerospace instrumentation
Procurement Notes
Verify the specific suffix 'SRU-EP' against the manufacturer's official ordering guide to confirm package type and tape/reel configuration. Ensure compliance with AQEC standards if required for defense or aerospace projects. Check for controlled manufacturing baseline and product change notification availability.
Selection Notes
Select this component for high-precision applications requiring 20-bit resolution and low drift (<0.05 ppm/°C). Consider the unbuffered output nature and potential need for external amplification. Verify supply voltage compatibility within the ±16.5 V range and ensure digital interface levels match the 1.8 V to 5.5 V IOVCC requirement.
Part Context
The AD5791-EP is part of Analog Devices' Enhanced Product line, designed for reliability in harsh environments. It shares core specifications with the standard AD5791 but offers controlled manufacturing sites and qualification data suitable for critical systems. The SRU-EP designation indicates a specific package and packaging variant within the EP family.
Replacement Considerations
The AD5781 is an 18-bit companion device with 0.5 LSB INL. Direct pin-compatible replacements should be verified through official cross-reference tools. No other direct substitutes are listed in the provided documentation.
