DAC122S085CIMM-NS

Digital To Analog Converters Overview

The DAC122S085CIMM is a dual-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments, which acquired National Semiconductor. It features a resistor string architecture with rail-to-rail voltage outputs and operates on a single supply voltage ranging from 2.7 V to 5.5 V. The device supports serial interfaces including SPI, Microwire, and QSPI, achieving a sampling rate of 2.5 MS/s. Key electrical specifications include a settling time of 6 µs, an integral nonlinearity (INL) of ±2.4 LSB, and a differential nonlinearity (DNL) of 0.2 LSB. It is housed in a compact MSOP-10 package and functions within a temperature range of -40°C to +105°C.

Digital To Analog Converters Feature Summary

• Dual-channel configuration with independent 12-bit resolution per channel
• Rail-to-rail buffered voltage outputs for maximum dynamic range

Digital To Analog Converters Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor was acquired by Texas Instruments. Ensure the component suffix matches current TI standards, typically ending in NOPB for lead-free compliance. Confirm that the specific ordering part number aligns with the desired package variant and thermal grade before procurement to avoid compatibility issues.

Digital To Analog Converters Selection Notes

Select this component when dual-channel performance is required in a minimal footprint. Compare INL and DNL specifications against application accuracy needs. Verify that the serial interface timing requirements match the host microcontroller capabilities. Consider the MSOP-10 package dimensions for PCB layout constraints relative to alternative packages like SON or VSSOP.

Digital To Analog Converters Part Context

This device belongs to the DAC122S085 family of micro-power converters. It shares architectural similarities with other members such as the DAC102S085 and DAC124S085, differing primarily in resolution and channel count. The transition from National Semiconductor branding to Texas Instruments reflects corporate integration while maintaining technical continuity in the datasheet specifications.

Digital To Analog Converters Replacement Considerations

DAC122S085CIMM/NOPB is the direct equivalent under Texas Instruments branding. DAC122S085CIMMX/NOPB offers the same functionality in a VSSOP-10 package. DAC122S085CISDX/NOPB provides a SON-10 package option for different board space requirements.
