Overview
The AD5696BCPZ-RL7 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 a 400 kHz I2C-compatible serial interface with 1.8 V logic compatibility. The device guarantees monotonicity by design and offers high relative accuracy with an INL of ±2 LSB maximum at 16 bits. Key specifications include a total unadjusted error (TUE) of ±0.1% FSR, offset error of ±1.5 mV, and a drive capability of 20 mA. It is housed in a 3 mm × 3 mm, 16-lead LFCSP package.
Feature Summary
- Quad-channel 16-bit resolution with ±2 LSB maximum INL
- I2C-compatible 2-wire serial interface supporting up to 400 kHz clock rates
- User-selectable gain of 1 or 2 via GAIN pin for flexible output ranges
- Power-on reset circuit with RSTSEL pin for zero-scale or midscale initialization
Applications
- Digital gain and offset adjustment
- Programmable attenuators
- Process control PLC I/O cards
- Industrial automation systems
- Data acquisition systems
Procurement Notes
Verify the B grade designation for specific accuracy parameters, including ±1 LSB INL typical performance. Confirm the LFCSP-16 package type and reel packaging format. Ensure compatibility with the required I2C bus speed and logic voltage levels before integration.
Selection Notes
Select this component when four independent 16-bit voltage outputs are required in a compact footprint. The B grade offers tighter accuracy specifications compared to the A grade. Consider the 20 mA output drive capability and capacitive load stability requirements for the application.
Part Context
This part belongs to the AD5696 series, which includes variants with internal or external references and different packages. The BCPZ suffix indicates the B grade accuracy level and the LFCSP-16 package. Other series members include the AD5696R with internal reference and the AD5696ARUZ in TSSOP-16.
Replacement Considerations
The AD5696ACPZ-RL7 and AD5696ARUZ-RL7 are direct functional equivalents within the same series, differing primarily in accuracy grade and package type. Verify that the substitute matches the required INL and TUE specifications.
