AD5663BCPZ-R2

Overview

The AD5663BCPZ-R2 is a dual-channel, 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 rail-to-rail output swing. The device guarantees monotonicity by design with a maximum relative accuracy of ±12 LSBs for the B grade. Key electrical parameters include a typical power consumption of 1.25 mW at 5 V, a settling time of 4 μs to 7 μs, and a serial interface supporting clock rates up to 50 MHz. It incorporates hardware LDAC and CLR functions alongside per-channel power-down modes.

Feature Summary

• Dual 16-bit resolution with ±12 LSB maximum relative accuracy
• Rail-to-rail output amplifiers operating within 2.7 V to 5.5 V supply range
• High-speed 3-wire serial interface compatible with SPI, QSPI, Microwire, and DSP standards
• Integrated power-on reset circuit ensuring outputs initialize to zero scale or midscale

Applications

• Process control systems requiring precise analog signal generation
• Data acquisition systems utilizing multi-channel input/output
• Portable battery-powered instruments benefiting from low power consumption
• Programmable voltage and current sources for calibration
• Digital gain and offset adjustment circuits

Procurement Notes

Verify the specific suffix 'R2' against the manufacturer's official ordering guide to confirm packaging configuration, as standard datasheets may list generic package options like MSOP or LFCSP_WD without detailing reel specifications. Ensure compatibility with required temperature grades and reference voltage configurations before finalizing procurement.

Selection Notes

Select this component when a dual-channel, high-precision DAC with external reference requirements is needed. The AD5663 requires an external reference voltage to set the output range, unlike the AD5663R series which includes an internal reference. Consider the 10-lead MSOP or LFCSP_WD packages based on board space constraints and thermal management needs.

Part Context

The AD5663 belongs to Analog Devices' nanoDAC family, designed for low-power applications. It serves as a counterpart to the AD5663R, differing primarily in the absence of an integrated voltage reference. This distinction allows designers to utilize custom external references for specific accuracy or range requirements while maintaining the same pinout and interface functionality.

Replacement Considerations

The AD5663BRMZ-1 is a variant within the same family that powers up to midscale instead of zero scale. For devices with integrated references, the AD5663R series offers similar performance but includes an on-chip 2.5 V reference.
