Overview
The AD5667BCPZ-R2 is a dual, 16-bit buffered voltage-output digital-to-analog converter (DAC) from the nanoDAC family. It operates on a single 2.7 V to 5.5 V supply and features an I2C-compatible serial interface supporting standard, fast, and high-speed modes. The device includes hardware LDAC and CLR functions, per-channel power-down capabilities, and a power-on reset circuit ensuring outputs start at zero scale. It is housed in a 3 mm x 3 mm LFCSP package.
Feature Summary
- Dual 16-bit resolution with guaranteed monotonicity by design
- I2C-compatible serial interface with up to 3.4 MHz clock speed
- Hardware LDAC and CLR pins for synchronized updates and clearing
- Per-channel power-down mode reducing current consumption to 480 nA at 5 V
Applications
- Process control systems
- Data acquisition systems
- Portable battery-powered instruments
- Digital gain and offset adjustment circuits
- Programmable voltage and current sources
Procurement Notes
Verify the specific suffix 'R2' against official documentation to confirm power-up behavior and internal reference status. Confirm package type matches the LFCSP-10 specification. Check RoHS compliance details as indicated in distributor listings. Ensure the ordering code aligns with the required temperature range of -40°C to +105°C.
Selection Notes
Select this component when dual-channel precision is required with minimal pin count. The external reference version requires an external voltage source for output range setting. Consider the AD5667R variant if an integrated 1.25 V or 2.5 V reference is needed. Verify I2C address configuration via the ADDR pin before integration.
Part Context
This part belongs to the AD5627/AD5667 nanoDAC series, which offers low-power, small-footprint solutions. It is distinct from the R-suffix versions that include on-chip references. The B grade indicates operation within the industrial temperature range. It serves as a compact alternative to larger parallel DACs in space-constrained designs.
Replacement Considerations
The AD5667BCPZ is the non-reel equivalent. For devices with internal references, consider the AD5667RBCPZ series. Other pin-compatible options in the nanoDAC family include the AD5627 and AD5647 variants with lower resolutions.
