Overview
The AD5694RBRUZ-RL7 is a quad, 12-bit buffered voltage output digital-to-analog converter (DAC) from the nanoDAC+ family. It integrates a 2.5 V internal 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 features a 400 kHz I2C-compatible serial interface and supports user-selectable gain settings of 1 or 2 via the GAIN pin, enabling full-scale outputs of 2.5 V or 5 V respectively. Key performance metrics include a maximum total unadjusted error (TUE) of ±0.1% of FSR, a settling time of 5 µs, and low power consumption of 3.3 mW at 3 V.
Feature Summary
- Quad 12-bit resolution with high relative accuracy (INL: ±1 LSB max).
- Integrated 2.5 V reference with 2 ppm/°C typical drift.
- User-selectable gain (×1 or ×2) for 2.5 V or 5 V full-scale output.
- 400 kHz I2C serial interface with 1.8 V logic compatibility.
Applications
- Optical transceivers
- Base-station power amplifiers
- Process control (PLC I/O cards)
- Industrial automation
- Data acquisition systems
Procurement Notes
Verify the specific suffix RL7 corresponds to the reel packaging format required for automated assembly. Confirm that the A Grade or B Grade selection matches the required INL and offset specifications for the application. Ensure the TSSOP-16 package dimensions align with the PCB footprint design constraints.
Selection Notes
Select this component when a quad-channel DAC with integrated precision reference is needed. The AD5694R offers 12-bit resolution; consider the AD5695R for 14-bit or AD5696R for 16-bit resolution if higher accuracy is required. Verify that the 2.7 V to 5.5 V supply range and 400 kHz I2C speed meet system requirements.
Part Context
This part belongs to the AD5696R/AD5695R/AD5694R family, which shares identical pinouts and functional blocks but differs in resolution. The 'R' designation indicates an internal reference, while 'BRUZ' specifies the 16-lead TSSOP package. The '-RL7' suffix denotes tape-and-reel packaging for surface-mount technology.
Replacement Considerations
The AD5694RARUZ is a compatible alternative in the same package with identical electrical characteristics. For higher resolution needs, the AD5695RBRUZ-RL7 (14-bit) and AD5696RBRUZ-RL7 (16-bit) are direct pin-compatible upgrades within the same series.
