AD5668BCBZ-1-500R7

Overview

The AD5668BCBZ-1-500R7 is an octal, 16-bit buffered voltage-output digital-to-analog converter (DAC) from Analog Devices. It operates on a single 2.7 V to 5.5 V supply and features an integrated 1.25 V reference with 5 ppm/°C temperature coefficient, providing a 2.5 V full-scale output range. The device includes a power-on reset circuit that initializes outputs to zero scale. It supports a versatile 3-wire serial interface compatible with SPI, QSPI, Microwire, and DSP standards, operating at clock rates up to 50 MHz. The part is housed in a 16-ball WLCSP package.

Feature Summary

• Octal architecture with 16-bit resolution and rail-to-rail buffered voltage outputs
• Integrated 1.25 V reference with 5 ppm/°C stability for 2.5 V full-scale range
• Power-on reset ensures outputs initialize to zero scale upon startup
• Low power consumption with power-down current of 400 nA at 5 V

Applications

• Process control systems
• Data acquisition systems
• Portable battery-powered instruments
• Programmable voltage and current sources

Procurement Notes

Verify the specific suffix -500R7 against official documentation to confirm reel packaging quantity and tape specifications. Ensure compatibility with the 16-ball WLCSP footprint during procurement planning.

Selection Notes

Select this component when eight independent 16-bit channels are required in a compact form factor. The internal 1.25 V reference suits applications needing a 2.5 V output span without external references. Verify thermal requirements for the WLCSP package in high-density designs.

Part Context

This part belongs to the AD5628/AD5648/AD5668 family of denseDACs. The AD5668 variant specifically provides 16-bit resolution. The B grade indicates tighter linearity specifications compared to the A grade, while the -1 suffix denotes the 1.25 V internal reference configuration.

Replacement Considerations

Check for pin-compatible alternatives within the same family, such as AD5668ARUZ or AD5668BRUZ, depending on the required package type (TSSOP/LFCSP vs. WLCSP). Verify if the reference voltage requirement matches the -1 (1.25 V) or -2/-3 (2.5 V) variants.
