Overview
The AD5669RBCPZ-1500R7 is an octal, 16-bit buffered voltage-output digital-to-analog converter (DAC) from the denseDAC family. It features an on-chip 1.25 V reference with a temperature coefficient of 5 ppm/°C, yielding a full-scale output range of 2.5 V. The device operates on a single 2.7 V to 5.5 V supply and supports I2C-compatible serial interfaces at standard (100 kHz) and fast (400 kHz) modes. Key specifications include a settling time of 7 µs, guaranteed monotonicity by design, and power-down currents as low as 400 nA at 5 V.
Feature Summary
- Octal architecture with 16-bit resolution and buffered voltage outputs
- Integrated 1.25 V reference providing 2.5 V full-scale output range
- I2C interface supporting standard and fast modes
- Power-on reset to zero scale or midscale
Applications
- Process control systems
- Data acquisition systems
- Portable battery-powered instruments
- Programmable voltage and current sources
Procurement Notes
Verify the specific suffix '1500R7' against official Analog Devices documentation to confirm reel quantity and packaging details, as datasheet ordering guides typically list standard suffixes like RL7. Ensure compatibility with the 16-lead LFCSP package requirements for thermal management and ground connection.
Selection Notes
Select this component when eight independent 16-bit channels are required in a compact form factor. The internal 1.25 V reference limits the maximum output swing to 2.5 V; use external references or higher-voltage variants if wider output ranges are needed. Verify that the system logic levels match the I2C interface requirements.
Part Context
This part belongs to the AD5629R/AD5669R denseDAC series, which offers low-power solutions for multi-channel applications. The 'BCPZ' designation indicates the B grade accuracy and LFCSP packaging, while the '-1' suffix specifies the 1.25 V internal reference configuration.
Replacement Considerations
Direct pin-compatible alternatives within the same family include the AD5669RACPZ-1-RL7 (TSSOP package) and AD5669RBCBZ-1-R5 (WLCSP package). These share identical electrical characteristics but differ in physical footprint and thermal performance.
