DAC124S085CISD/NOPB

Digital To Analog Converters Overview

The DAC124S085CISD/NOPB is a quad-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features a resistor-string architecture with voltage-buffered outputs and supports serial interfaces including SPI, QSPI, Microwire, and DSP modes. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V for both analog and digital domains. Key performance metrics include a sampling rate of 2.5 MS/s per channel, a settling time of 6 µs, and a typical power consumption of 1.1 mW. It is housed in a WSON-10 package and functions within an industrial temperature range of -40°C to +105°C.

Digital To Analog Converters Feature Summary

• Integrates four independent 12-bit DAC channels with internal voltage buffers for direct drive capability.
• Supports flexible digital interface compatibility with standard SPI, QSPI, Microwire, and DSP protocols.
• Optimized for low power consumption and small footprint suitable for space-constrained designs.

Digital To Analog Converters Applications

• Battery-powered instrumentation systems requiring low power and high accuracy.
• Industrial process control loops utilizing serial communication buses.
• Portable medical devices needing compact form factor and multi-channel signal generation.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'CISD' corresponds to the WSON-10 package and industrial temperature grade (-40°C to +105°C). Confirm that the 'NOPB' designation indicates lead-free and RoHS compliance as per Texas Instruments standards. Ensure the ordering quantity matches the manufacturer's tape and reel specifications for this specific package variant.

Digital To Analog Converters Selection Notes

Select this component when four isolated 12-bit output channels are required in a minimal footprint. Compare against the DAC124S085CIMM/NOPB if an MSOP-10 package is preferred instead of WSON-10. Verify that the 2.5 MS/s update rate and 6 µs settling time meet the system bandwidth requirements. Ensure the 2.7 V to 5.5 V supply range aligns with the available power rails in the target application.

Digital To Analog Converters Part Context

This part belongs to the DAC124S085 family of micro-power, quad-channel DACs. It shares architectural similarities with the 2-channel DAC122S085 and the 8-channel DAC128S085 variants. All members utilize a resistor-string architecture and support similar serial interfaces, differing primarily in channel count and physical package options such as WSON or MSOP.

Digital To Analog Converters Replacement Considerations

DAC124S085CIMM/NOPB offers identical electrical specifications but utilizes an MSOP-10 package instead of WSON-10. DAC122S085CISD/NOPB provides two channels with similar performance in the same WSON-10 package. DAC128S085CIMT/NOPB provides eight channels in a TSSOP-16 package.
