AD5693RACPZ-RL7

Overview

The AD5693RACPZ-RL7 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 operates on a single 2.7 V to 5.5 V supply. The device supports I2C serial communication and offers selectable output spans of 0 V to VREF or 0 V to 2 × VREF. Key electrical parameters include a maximum settling time of 5 µs, ±2 LSB INL (B Grade), and a power consumption of 1.2 mW at 3.3 V in normal mode. 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) and ±1 LSB DNL
• Integrated low-drift 2.5 V reference (2 ppm/°C typical)
• I2C serial interface with software-selectable gain (×1 or ×2)
• Low power operation: 1.2 mW at 3.3 V; 2 µA max in power-down mode

Applications

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

Procurement Notes

Verify the specific grade (A or B) and pin configuration (LDAC, RESET, or VLOGIC option) required for the design, as these are determined by the full ordering suffix beyond the base model number. Confirm that the 8-lead LFCSP package meets the thermal and mechanical constraints of the target PCB layout.

Selection Notes

Select this component when high relative accuracy and low power are critical in a small footprint. Ensure the application requires a single-channel DAC with I2C connectivity. Verify that the supply voltage range (2.7 V to 5.5 V) and logic levels are compatible with the system controller. Consider the external reference variant if lower temperature drift than the internal reference is needed.

Part Context

This part belongs to the AD5693R/AD5692R/AD5691R/AD5693 nanoDAC+ family, which provides 16-, 14-, and 12-bit resolution options. The AD5693R specifically denotes the 16-bit version with an internal reference. Other family members include the SPI-based AD5683R and the external reference AD5693.

Replacement Considerations

Direct replacements within the same package and functionality include other variants from the AD5693R family with different pinout options (e.g., AD5693RBRMZ). For SPI interfaces, the AD5683R series is functionally similar but requires interface adaptation.
