Overview
The AD5696ACPZ-RL7 is a quad, 16-bit buffered voltage output digital-to-analog converter (DAC) from the nanoDAC+ family. It features a 2-wire I2C-compatible serial interface operating at clock rates up to 400 kHz. The device operates from a single 2.7 V to 5.5 V supply and includes a user-selectable gain pin for full-scale outputs of 2.5 V or 5 V. Key electrical specifications include a maximum integral nonlinearity (INL) of ±2 LSB, a total unadjusted error (TUE) of ±0.1% FSR, and an offset error of ±1.5 mV. It is housed in a 3 mm × 3 mm, 16-lead LFCSP package.
Feature Summary
- Quad 16-bit resolution with high relative accuracy (±2 LSB INL max).
- I2C-compatible serial interface supporting standard (100 kHz) and fast (400 kHz) modes.
- User-selectable gain (1 or 2) via GAIN pin for flexible output span.
- Integrated power-on reset circuit with RSTSEL pin for zero-scale or midscale initialization.
Applications
- Digital gain and offset adjustment circuits.
- Programmable attenuators.
- Process control PLC I/O cards.
- Industrial automation systems.
- Data acquisition systems.
Procurement Notes
Verify the specific grade (A or B) required for the application, as performance parameters such as INL and offset error vary between grades. Confirm that the LFCSP-16 package meets the PCB footprint requirements. Ensure the design accounts for the exposed pad connection to ground for thermal management and electrical grounding.
Selection Notes
Select this component when four independent 16-bit channels are required with low power consumption and high DC accuracy. Compare against the AD5696R if internal reference stability is critical, as the AD5696 requires an external reference. Verify logic voltage compatibility (1.8 V/3 V/5 V) via the VLOGIC pin for microprocessor interfacing.
Part Context
This part belongs to the AD5696 series, which shares architecture with the AD5694 (12-bit) and AD5696R (internal reference). The 'ACPZ' suffix denotes the 16-lead LFCSP package, while 'RL7' indicates reel packaging. It is distinct from SPI-interface variants like the AD5686.
Replacement Considerations
The AD5696ARUZ-RL7 offers identical functionality in a 16-lead TSSOP package. For applications requiring an internal reference, the AD5696RBCPZ-RL7 is a functional equivalent with improved reference stability.
