AD5693BCPZ-RL7

Overview

The AD5693BCPZ-RL7 is a single-channel, 16-bit buffered voltage output digital-to-analog converter (DAC) from the nanoDAC+ family. It operates on a single supply of 2.7 V to 5.5 V and features an I2C serial interface. The device includes an internal 2.5 V reference with a typical drift of 2 ppm/°C. Key electrical specifications include a maximum integral nonlinearity (INL) of ±2 LSB at 16 bits, a settling time of 5 µs, and a low power consumption of 1.2 mW at 3.3 V. It supports selectable output spans of VREF or 2 × VREF and offers a shutdown mode reducing current to 2 µA.

Feature Summary

• 16-bit resolution with ±2 LSB maximum INL (B Grade)
• Internal 2.5 V reference with 2 ppm/°C typical drift
• I2C serial interface with software programmable gain (×1 or ×2)
• Ultrasmall 8-lead LFCSP package (2 mm × 2 mm)

Applications

• Process controls
• Data acquisition systems
• Digital gain and offset adjustment
• Programmable voltage sources
• Optical modules

Procurement Notes

Verify the specific grade (B Grade) and package variant against the datasheet ordering guide. Confirm that the I2C address configuration matches the system requirements. Ensure the external reference decoupling capacitor value meets the recommendation if using the internal reference output.

Selection Notes

Select this component for applications requiring high relative accuracy in a small footprint. The B Grade ensures tighter INL specifications compared to A Grade options. Consider the power-down mode for battery-operated systems where 2 µA standby current is critical. Verify compatibility with 1.8 V logic levels if the VLOGIC pin is utilized.

Part Context

This part belongs to the AD5693R/AD5692R/AD5691R/AD5693 family. The AD5693 variant specifically uses an external reference input, while the AD5693R includes an internal reference. The 'BCPZ' suffix indicates the B Grade accuracy and LFCSP-8 package. The '-RL7' suffix denotes reel packaging.
