AD5791SRUZ-EP

Overview

The AD5791SRUZ-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 33 V and features 1 ppm resolution with ±1 LSB INL and DNL. The device supports a 3-wire serial interface at 35 MHz, includes power-on reset logic, and offers low noise of 7.5 nV/√Hz. Designed for military environments, it functions within −55°C to +125°C.

Feature Summary

• 20-bit resolution with 1 ppm INL and ±1 LSB DNL
• Military temperature range: −55°C to +125°C
• Wide bipolar supply range up to ±16.5 V
• Enhanced Product (EP) controlled manufacturing baseline

Applications

• Medical instrumentation
• Test and measurement
• Industrial control
• High-end scientific and aerospace instrumentation

Procurement Notes

Verify the specific SRUZ-EP suffix against the manufacturer's current ordering guide to confirm package type and tape/reel configuration. Ensure the design meets AQEC standards if defense qualification data is required.

Selection Notes

Select this component for applications requiring high precision in harsh environments. Use external op amps like the AD8676 for reference buffering and AD8675 for output buffering to achieve specified linearity and noise performance.

Part Context

This part belongs to the AD5791-EP Enhanced Product family, designed for defense and aerospace markets. It shares core specifications with the commercial AD5791 but adds controlled manufacturing sites and product change notifications.

Replacement Considerations

The AD5781 is an 18-bit alternative within the same family. Verify pin compatibility and interface requirements when substituting.
