AD5696BRUZ-RL7

Overview

The AD5696BRUZ-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. Key specifications include ±2 LSB maximum integral nonlinearity, ±0.1% FSR gain error, and ±1.5 mV offset error. The device offers user-selectable gain of 1 or 2 via the GAIN pin, ensuring full-scale outputs of 0 V to VREF or 0 V to 2 × VREF. It incorporates power-on reset functionality and per-channel power-down modes.

Feature Summary

• Quad 16-bit resolution with high relative accuracy (±2 LSB INL max).
• I2C-compatible 2-wire serial interface supporting up to 400 kHz clock rates.
• User-selectable gain configuration (Gain = 1 or 2) via external pin.
• Integrated power-on reset circuit with RSTSEL pin for zero 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) associated with the BRUZ suffix against the manufacturer's ordering guide, as performance parameters like INL vary by grade. Confirm that the RL7 suffix corresponds to the reel packaging format required for automated assembly processes. Ensure the design supports the 16-TSSOP package dimensions and thermal requirements specified in the datasheet outline.

Selection Notes

Select this component when a quad-channel, 16-bit DAC with I2C connectivity is required. The AD5696 provides higher resolution than the AD5694 (12-bit) but lacks an internal reference; use the AD5696R if an integrated reference is needed. Consider the TSSOP package for through-hole or standard SMT applications where LFCSP is unsuitable. Verify that the application load does not exceed the 20 mA drive capability or 2 nF capacitive load stability limits.

Part Context

This part belongs to the AD5696/AD5694 nanoDAC+ series, which are low-power, quad-channel devices. The AD5696 variant specifically offers 16-bit resolution, distinguishing it from the 12-bit AD5694. The series is characterized by its small footprint options and robust DC performance, including guaranteed monotonicity by design. It serves as a bridge between digital control systems and analog signal generation in precision applications.

Replacement Considerations

The AD5696ARUZ-RL7 is a lower-grade alternative within the same package and interface family. For devices with an integrated reference, consider the AD5696R series. The AD5695R offers 14-bit resolution with an internal reference. Ensure any substitute maintains the 16-TSSOP footprint and I2C protocol compatibility.
