AD5693RBCPZ-2RL7

Overview

The AD5693RBCPZ-2RL7 is a single-channel, 16-bit buffered voltage output digital-to-analog converter (DAC) from the nanoDAC+ family. It features an internal 2.5 V reference with a typical drift of 2 ppm/°C and supports selectable output spans of 0 V to VREF or 0 V to 2 × VREF. The device operates on a single 2.7 V to 5.5 V supply and communicates via an I2C interface. Key electrical specifications include a maximum integral nonlinearity (INL) of ±2 LSB for B grade, a settling time of 5 µs, and a low power consumption of 1.2 mW at 3.3 V. It is housed in an ultrasmall 2 mm × 2 mm, 8-lead LFCSP package.

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 (2 mm × 2 mm) package

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm pinout options such as RESET or VLOGIC availability. Ensure the selected variant matches the required package type and performance grade for the intended application environment.

Selection Notes

Select this component for applications requiring high relative accuracy in a minimal footprint. The internal reference simplifies design by eliminating external components, while the I2C interface reduces pin count. Consider the power-down mode for battery-operated systems where 2 µA standby current is critical.

Part Context

This part belongs to the AD5693R/AD5692R/AD5691R series, which offers 16-bit, 14-bit, and 12-bit resolutions respectively. The 'R' designation indicates the inclusion of an internal reference, distinguishing it from the AD5693 model which requires an external reference. The 'BCPZ' suffix denotes the B-grade accuracy and LFCSP packaging.

Replacement Considerations

Direct substitutes within the same family include the AD5692R (14-bit) and AD5691R (12-bit) for lower resolution needs, or the AD5693 (external reference) if the internal reference is not desired. Cross-family SPI-compatible alternatives like the AD5683R offer similar performance with a different interface.
