DAC102S085CISD/NOPB

Digital To Analog Converters Overview

The DAC102S085CISD/NOPB is a dual-channel, 10-bit digital-to-analog converter manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2.7V to 5.5V for both analog and digital domains. The device features buffered voltage outputs and supports serial interfaces including SPI, DSP, Microwire, and QSPI. Key performance metrics include a settling time of 4.5 nanoseconds, a maximum integral nonlinearity of ±0.7 LSB, and a differential nonlinearity of 0.08 LSB. Power consumption is specified at 600 µW. It functions within an industrial temperature range of -40°C to +105°C and is housed in a compact 10-WSON package.

Digital To Analog Converters Feature Summary

• Dual-channel architecture providing two independent 10-bit DACs in a single component
• Low power consumption design suitable for battery-operated applications
• Flexible serial interface compatibility with standard communication protocols
• High-speed operation with rapid settling time for dynamic signal generation

Digital To Analog Converters Applications

• Portable instrumentation requiring low power and small form factor
• Battery-powered data acquisition systems
• Industrial process control loops
• Programmable gain amplifiers and variable voltage references

Digital To Analog Converters Procurement Notes

Verify the specific suffix configuration when sourcing replacements, as packaging or temperature grades may differ. Confirm that the target application environment remains within the specified -40°C to +105°C operating range. Ensure supply voltage levels do not exceed the 5.5V maximum limit for both analog and digital supplies. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Digital To Analog Converters Selection Notes

Select this component when dual-channel conversion is required without increasing board space. Compare against single-channel alternatives if only one output is needed to reduce cost. Consider the 10-bit resolution limits for applications requiring higher precision. Evaluate the serial interface requirements to ensure compatibility with the host microcontroller's available ports.

Digital To Analog Converters Part Context

This part belongs to the DAC102S085 family of micro-power dual DACs. It shares architectural similarities with other members like the DAC102S085CISD but includes the NOPB suffix indicating lead-free and RoHS-compliant manufacturing. The series is designed for cost-sensitive, space-constrained embedded systems requiring moderate speed and resolution.

Digital To Analog Converters Replacement Considerations

The DAC102S085CISD is listed as a direct functional substitute. Verify pinout compatibility and electrical specifications before substitution. Ensure the replacement part meets the same thermal and voltage requirements.
