AD5663BCPZ-REEL7

Overview

The AD5663BCPZ-REEL7 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 rail-to-rail output swing with a maximum relative accuracy of ±12 LSBs. The device guarantees monotonicity by design and includes hardware LDAC and CLR functions. It utilizes a versatile 3-wire serial interface compatible with SPI, QSPI, Microwire, and DSP standards, supporting clock rates up to 50 MHz. Power consumption is typically 1.25 mW at 5 V, reducing to 480 nA in power-down mode.

Feature Summary

• Dual-channel 16-bit resolution with ±12 LSBs maximum relative accuracy
• Rail-to-rail output capability with 2.7 V to 5.5 V single-supply operation
• Guaranteed monotonic by design architecture
• Per-channel power-down modes reducing current 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 grade suffix 'B' against the datasheet Ordering Guide to confirm performance parameters such as relative accuracy limits. Confirm that the 'REEL7' suffix corresponds to the required tape-and-reel packaging quantity for manufacturing integration. Ensure external reference voltage requirements are met, as this component requires an external VREF input.

Selection Notes

Select this component when dual-channel precision is required without an internal reference. The AD5663 relies on an external reference voltage to set the output range. Compare the ±12 LSBs accuracy specification against system requirements; higher accuracy grades may require different part numbers within the AD5663 family. Verify compatibility with the host microcontroller's serial interface timing constraints.

Part Context

This part belongs to the AD5663 nanoDAC family, which also includes variants with internal references (AD5663R). The BC designation indicates a specific temperature and accuracy grade within the industrial range (-40°C to +105°C). It is distinct from the quad-channel AD5666 or the lower-resolution AD5623/AD5643 series.

Replacement Considerations

Direct replacements include other AD5663 variants with different package options (e.g., MSOP) or internal reference configurations (AD5663R), provided pinout and functionality remain compatible. Cross-reference specific grade suffixes for accuracy matching.
