Overview
The AD5695RBRUZ is a quad, 14-bit buffered voltage output Digital-to-Analog Converter (DAC) from Analog Devices. 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 a 400 kHz I2C-compatible serial interface and includes a GAIN pin for selectable full-scale outputs of 2.5 V or 5 V. Key performance metrics include a maximum relative accuracy (INL) of ±1 LSB, a settling time of 8 µs, and low power consumption of 3.3 mW at 3 V.
Feature Summary
- Quad 14-bit resolution with ±1 LSB maximum INL
- Integrated 2.5 V reference with 2 ppm/°C temperature coefficient
- User-selectable gain of 1 or 2 via the GAIN pin
- Power-on reset circuit with RSTSEL pin for zero/midscale initialization
Applications
- Optical transceivers
- Base-station power amplifiers
- Process control PLC I/O cards
- Industrial automation systems
- Data acquisition systems
Procurement Notes
Verify the specific package variant against the datasheet; the BRU suffix indicates a 16-lead TSSOP package. Confirm that the internal reference is enabled by default and check the A/B grade requirements for INL specifications. Ensure the logic voltage range (VLOGIC) supports the system's microprocessor levels between 1.62 V and 5.5 V.
Selection Notes
Select this component when a quad-channel DAC with high relative accuracy and low drift is required. The AD5695R offers 14-bit resolution, suitable for applications needing better than 12-bit precision but not requiring the full 16-bit capability of the AD5696R. Consider the 2.7 V to 5.5 V supply range and the 400 kHz I2C interface speed for system compatibility.
Part Context
The AD5695RBRUZ belongs to the nanoDAC+ family, which also includes the 16-bit AD5696R and the 12-bit AD5694R. These devices share identical pinouts, interfaces, and general features, differing primarily in resolution and associated accuracy specifications. The BRU suffix specifically denotes the 16-lead TSSOP package option available for this series.
Replacement Considerations
The AD5696RARUZ serves as a higher-resolution replacement within the same package. For lower resolution needs, the AD5694ARUZ is compatible. Verify that any substitute maintains the 16-lead TSSOP footprint and I2C interface requirements.
