DAC124S085CIMM/NOPB

Digital To Analog Converters Overview

The DAC124S085CIMM/NOPB is a quad-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 serial interfaces including SPI, QSPI, Microwire, and DSP modes. Key electrical specifications include a sampling rate of 2.5 MS/s, a settling time of 6 µs, and a power dissipation of 1.1 mW. Linearity performance features a differential nonlinearity (DNL) of 0.2 LSB and an integral nonlinearity (INL) of ±2.4 LSB. The gain error is specified at 1% FSR. It is housed in a 10-pin MSOP package and functions across an operating temperature range from -40°C to +105°C.

Digital To Analog Converters Feature Summary

• Integrates four independent 12-bit voltage-output DACs with internal buffers in a compact footprint.
• Supports high-speed serial communication via standard SPI, QSPI, Microwire, and DSP interface protocols.
• Optimized for low power consumption while maintaining small physical size for space-constrained designs.

Digital To Analog Converters Applications

• Battery-powered instrumentation systems requiring multi-channel signal generation.
• Industrial process control loops utilizing serial bus architectures.
• Portable medical devices needing precise analog output with minimal power draw.

Digital To Analog Converters Procurement Notes

Verify the complete part number including the NOPB suffix to ensure lead-free compliance and specific packaging options. Confirm the MSOP-10 package variant matches the target PCB footprint. Check the datasheet for the latest revision history to ensure compatibility with existing design constraints. Validate that the required serial interface mode aligns with the host controller's capabilities.

Digital To Analog Converters Selection Notes

Select this component when four independent 12-bit channels are required in a single package. Compare against the DAC082S085 for lower resolution needs or the DAC121C085 for I2C connectivity. Ensure the 2.5 MS/s speed meets system timing requirements. Verify that the 1% FSR gain error fits the application accuracy budget.

Digital To Analog Converters Part Context

This device belongs to the DACxS085 family of micro-power DACs from Texas Instruments. It shares the same pinout and interface characteristics with other members like the DAC084S085 and DAC124S085, differing primarily in resolution and channel count. The CIMM suffix indicates commercial temperature range and MSOP packaging.

Digital To Analog Converters Replacement Considerations

The DAC124S085CIMMX/NOPB is a direct functional substitute with identical electrical specifications. Other family members such as the DAC084S085 offer similar interfaces but with 8-bit resolution. Cross-referencing the datasheet is recommended to confirm pin compatibility and thermal performance.
