AD5697RBCPZ-RL7

Overview

The AD5697RBCPZ-RL7 is a dual, 12-bit buffered voltage output digital-to-analog converter (DAC) from the nanoDAC+ family. It features an integrated 2.5 V reference with a typical temperature coefficient 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 a user-selectable gain pin for full-scale outputs of 2.5 V or 5 V. Packaged in a 3 mm × 3 mm 16-lead LFCSP, it offers low power consumption of 3.3 mW at 3 V and supports per-channel power-down modes.

Feature Summary

• Dual 12-bit resolution with Total Unadjusted Error (TUE) of ±0.1% FSR maximum
• Integrated 2.5 V reference with 2 ppm/°C typical drift
• User-selectable gain of 1 or 2 via GAIN pin
• Power-on reset circuit with RSTSEL pin for zero or midscale initialization

Applications

• Base station power amplifiers
• Process controls including programmable logic controller I/O cards
• Industrial automation systems
• Data acquisition systems

Procurement Notes

Verify the package type matches the specific suffix; the BC part number indicates the 16-lead LFCSP variant. Confirm that the RL7 suffix corresponds to the reel packaging format required for automated assembly processes. Ensure compatibility with the intended I2C bus speed and logic voltage levels before procurement.

Selection Notes

Select this component when a compact dual-channel DAC with high precision is required. The internal 2.5 V reference eliminates the need for external components, reducing board space. Consider the GAIN pin configuration to determine if the 0–2.5 V or 0–5 V output range suits the application requirements.

Part Context

This device belongs to the nanoDAC+ family, which focuses on low power and small form factors. The AD5697R is the dual-channel counterpart to single-channel variants like the AD5696R. The BC suffix specifically denotes the Lead-free LFCSP package, distinguishing it from TSSOP options.

Replacement Considerations

The AD5696R serves as a single-channel alternative within the same family. For applications requiring higher resolution, the AD5698R or AD5699R provide 14-bit and 16-bit options respectively, though they may require different pin configurations.
