AD5693RBRMZ-RL7

Overview

The AD5693RBRMZ-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 utilizes an I2C serial interface and offers selectable output spans of 0 V to VREF or 0 V to 2 × VREF. 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 a 10-lead MSOP package.

Feature Summary

• 16-bit resolution with ±2 LSB maximum INL (B Grade)
• Internal 2.5 V reference with 2 ppm/°C typical temperature coefficient
• 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

Procurement Notes

Verify the specific grade (A or B) and pin configuration options (LDAC, RESET, or VLOGIC variants) against the datasheet ordering guide, as suffixes indicate functional differences. Confirm RoHS compliance status and ensure the supplier provides valid traceability documentation for Analog Devices components.

Selection Notes

Select this component when high relative accuracy (±2 LSB INL) and low drift are required in a small footprint. Ensure the application supports the I2C interface and that the supply voltage range (2.7 V to 5.5 V) matches the system design. Consider the external reference variant (AD5693) if an internal reference is not desired.

Part Context

This part belongs to the AD5693R/AD5692R/AD5691R/AD5693 family, which includes 16-bit, 14-bit, and 12-bit resolutions. The 'R' suffix denotes an internal reference, while 'BRMZ' indicates the 10-lead MSOP package. Other family members like the AD5683 series use SPI interfaces.

Replacement Considerations

Publicly confirmed substitutes include other members of the nanoDAC+ family such as the AD5692R (14-bit) or AD5691R (12-bit) for lower resolution needs, or the AD5693 (external reference) if the internal reference is unsuitable. Verify pin compatibility and interface requirements before substitution.
