Overview
The AD5676RACPZ-REEL7 is an octal, 16-bit buffered voltage output digital-to-analog converter (DAC) from Analog Devices. It features a low-drift 2.5 V internal reference with a typical temperature coefficient of 2 ppm/°C and user-selectable gain of 1 or 2, providing full-scale outputs of 2.5 V or 5 V. The device operates on a single 2.7 V to 5.5 V supply and supports a 50 MHz SPI interface with readback or daisy-chain capabilities. Packaged in a 20-lead LFCSP, it includes a power-on reset circuit and a RSTSEL pin for configurable startup states.
Feature Summary
- Octal architecture with 16-bit resolution and ±3 LSB maximum INL
- Integrated 2.5 V reference with 2 ppm/°C drift
- User-selectable gain (1x or 2x) via GAIN pin or bit
- 50 MHz SPI interface with daisy-chain and readback support
Applications
- Optical transceivers
- Base station power amplifiers
- Process control PLC input/output cards
- Industrial automation systems
- Data acquisition systems
Procurement Notes
Verify the specific suffix 'ACPZ' against the manufacturer's ordering guide to confirm the package type (LFCSP) and grade. Ensure the reel quantity matches project requirements. Confirm RoHS compliance status as indicated in the datasheet documentation.
Selection Notes
Select this component when high channel density and precision are required in a small footprint. The LFCSP package offers thermal performance suitable for industrial environments. Consider the WLCSP option if board space is extremely constrained, noting potential differences in offset error drift specifications between packages.
Part Context
This part belongs to the nanoDAC+ family, designed for applications requiring multiple channels with high relative accuracy. It complements other devices like the AD5672R (12-bit) and AD5686R (quad-channel) within the same ecosystem, sharing similar interface protocols and reference architectures.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Direct pin-to-pin replacements should be verified through official Analog Devices cross-reference tools.
