Overview
The AD5686RTCPZ-EP-RL7 is a quad, 16-bit buffered voltage output digital-to-analog converter (DAC) from the nanoDAC+ family. It features a 2.5 V internal reference with 4 ppm/°C drift and supports SPI interfaces up to 50 MHz. The device operates on a single 2.7 V to 5.5 V supply with 1.8 V logic compatibility. Key specifications include ±4 LSB maximum INL, 15 mA drive capability, and power-down modes consuming 4 μA. It is housed in a 3 mm × 3 mm 16-lead LFCSP package.
Feature Summary
- Quad 16-bit resolution with ±4 LSB maximum integral nonlinearity (INL).
- Integrated 2.5 V reference with 4 ppm/°C typical temperature coefficient.
- Enhanced product qualification for defense and aerospace applications (-55°C to +125°C).
- User-selectable gain of 1 or 2 via GAIN pin for 2.5 V or 5 V full-scale outputs.
Applications
- Optical transceivers
- Base-station power amplifiers
- Process control PLC input/output cards
- Industrial automation systems
Procurement Notes
Verify the EP suffix indicates enhanced product status suitable for defense/aerospace contexts. Confirm the -RL7 suffix denotes reel packaging. Check for controlled manufacturing baseline requirements and available qualification data directly from Analog Devices for specific project compliance needs.
Selection Notes
Select this component when extended temperature range (-55°C to +125°C) and enhanced reliability are required. Ensure the 3 mm × 3 mm LFCSP package fits the PCB layout constraints. Verify that the 15 mA output drive current meets the load requirements for all four channels simultaneously.
Part Context
This part belongs to the AD5686R-EP Enhanced Product line, distinct from standard commercial variants by its qualified manufacturing baseline and wider operating temperature range. It shares functional similarities with the AD5686R but targets high-reliability sectors requiring controlled production sites.
Replacement Considerations
Standard AD5686RTCPZ-RL7 offers identical electrical performance but lacks the enhanced product qualification and extended temperature range. Verify if the EP-specific reliability requirements can be met by the commercial grade version.
