DAC122S085CISD/NOPB

Digital To Analog Converters Overview

The DAC122S085CISD/NOPB is a dual-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It operates within an analog and digital supply voltage range of 2.7 V to 5.5 V. The device supports a sampling rate of 2.5 MS/s with a settling time of 6 µs. It features a buffered voltage output and accepts serial interfaces including SPI, QSPI, Microwire, DSP, and 3-Wire protocols. Packaged in a WSON-10 form factor, it functions between -40°C and +105°C. Key performance metrics include a differential nonlinearity (DNL) of 0.2 LSB, integral nonlinearity (INL) of ±2.4 LSB, and a gain error of 1% FSR. Power consumption is rated at 600 µW.

Digital To Analog Converters Feature Summary

• Dual-channel architecture providing two independent 12-bit DAC outputs in a compact package.
• Integrated voltage buffer amplifiers for direct drive capability without external components.
• Flexible serial interface compatibility supporting multiple standard communication protocols.
• Low power operation suitable for battery-powered and space-constrained applications.

Digital To Analog Converters Applications

• Portable instrumentation requiring low power consumption
• Battery-operated data acquisition systems
• Industrial process control loops
• Programmable voltage references

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'CISD' confirms the commercial temperature grade (-40°C to +105°C) and WSON-10 package variant. Ensure the 'NOPB' designation indicates lead-free/RoHS compliance as per manufacturer specifications. Cross-reference the datasheet revision date to confirm interface timing parameters match your system requirements before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when dual-channel conversion is required alongside strict power budget constraints. Compare against single-channel variants if only one output is needed to optimize cost. Verify that the 2.5 MS/s speed meets system bandwidth needs. Ensure the serial interface protocol matches the host microcontroller's available peripherals to simplify software integration.

Digital To Analog Converters Part Context

This part belongs to the DAC122S085 series, which focuses on micro-power performance. It complements higher-channel-count models like the DAC124S085 or DAC128S085 by offering a balanced solution for dual-channel applications. The series utilizes a resistor string architecture to achieve specified linearity while maintaining low static power dissipation.

Digital To Analog Converters Replacement Considerations

The DAC122S085CISDX/NOPB is a parameter-equivalent alternative featuring a tape-and-reel packaging format instead of cut tape or other bulk options. Both parts share identical electrical characteristics and pinouts, allowing for direct substitution in existing designs where reel-based assembly is preferred.
