Overview
The AD5665BCPZ-R2 is a quad, 16-bit buffered voltage-output digital-to-analog converter (DAC) from the nanoDAC family. It operates on a single 2.7 V to 5.5 V supply and features an I2C-compatible serial interface supporting standard, fast, and high-speed modes. The device includes an on-chip 2.5 V reference with a temperature coefficient of 10 ppm/°C in the LFCSP package, enabling a full-scale output range of 5 V. It guarantees monotonicity by design and incorporates power-on reset logic to ensure outputs start at zero scale or midscale.
Feature Summary
- Quad 16-bit resolution with ±8 LSB relative accuracy
- On-chip 2.5 V reference (10 ppm/°C in LFCSP)
- I2C interface with up to 3.4 MHz high-speed mode
- Rail-to-rail output swing with per-channel power-down
Applications
- Process control systems
- Data acquisition systems
- Portable battery-powered instruments
- Digital gain and offset adjustment
- Programmable voltage and current sources
Procurement Notes
Verify the specific suffix 'R2' against the manufacturer's official ordering guide to confirm packaging details and availability status. Confirm that the LFCSP-10 package matches the target PCB footprint requirements. Ensure the internal reference configuration aligns with the system's voltage span needs.
Selection Notes
Select this component for applications requiring four independent 16-bit channels with low power consumption. The internal 2.5 V reference simplifies design by eliminating external precision references. Consider the 10 ppm/°C drift specification if operating in environments with significant temperature variations compared to the 5 ppm/°C TSSOP variant.
Part Context
This part belongs to the AD5625R/AD5645R/AD5665R series of nanoDACs. It shares pinout compatibility with the AD5625R and AD5645R variants, which offer 12-bit and 14-bit resolutions respectively. The 'R' suffix indicates the presence of an on-chip reference, while 'BCPZ' denotes the B-grade performance level and LFCSP-10 package.
Replacement Considerations
The AD5665BRUZ-2 is a pin-compatible alternative in a 14-lead TSSOP package with a 5 ppm/°C reference. For SPI interface requirements, consider the AD5664R series. Dual-channel equivalents include the AD5667R.
