Overview
The AD5696RBCPZ-RL7 is a quad, 16-bit buffered voltage output digital-to-analog converter (DAC) from the nanoDAC+ family. It features an integrated 2.5 V reference with a typical drift of 2 ppm/°C and operates on a single 2.7 V to 5.5 V supply. The device utilizes a 400 kHz I2C-compatible serial interface and includes user-selectable gain settings of 1 or 2 via the GAIN pin. Key performance metrics include a maximum relative accuracy (INL) of ±2 LSB, a total unadjusted error (TUE) of ±0.1% FSR, and a low glitch impulse of 0.5 nV-sec. It is housed in a compact 3 mm × 3 mm, 16-lead LFCSP package.
Feature Summary
- Quad 16-bit resolution with high relative accuracy (±2 LSB max INL).
- Integrated 2.5 V reference with 2 ppm/°C typical temperature coefficient.
- User-selectable gain of 1 (0 V to VREF) or 2 (0 V to 2×VREF).
- Power-on reset circuit with RSTSEL pin for zero-scale or midscale initialization.
Applications
- Optical transceivers
- Base-station power amplifiers
- Process control (PLC I/O cards)
- Industrial automation
- Data acquisition systems
Procurement Notes
Verify the specific grade (A or B) and suffix configuration against the manufacturer's ordering guide, as parameters such as relative accuracy and offset error vary between grades. Confirm that the LFCSP package requires proper thermal management and grounding of the exposed pad during assembly.
Selection Notes
Select this component when a quad-channel DAC with high precision and low drift is required. Ensure the supply voltage supports the desired gain setting; Gain = 2 requires VDD ≥ VREF + 1.5 V. Verify logic compatibility with the VLOGIC pin if interfacing with 1.8 V systems.
Part Context
This part belongs to the AD5696R/AD5695R/AD5694R family, which shares identical pinouts and interfaces but differs in resolution (16-bit, 14-bit, and 12-bit respectively). The 'RL7' suffix indicates tape and reel packaging, while 'BCPZ' denotes the LFCSP package and lead-free composition.
Replacement Considerations
The AD5696ACPZ-RL7 is a direct functional substitute within the same family, offering identical specifications and pinout compatibility in the LFCSP package.
