DAC102S085CISD

Digital To Analog Converters Overview

The DAC102S085CISD is a dual 10-bit micro-power digital-to-analog converter manufactured by Texas Instruments, formerly National Semiconductor. It operates on a single supply voltage ranging from 2.7 V to 5.5 V for both analog and digital domains. The device features buffered voltage outputs with a maximum settling time of 6 µs. It supports serial interfaces including SPI, DSP, Microwire, and QSPI. The component is housed in a 10-WSON (3x3 mm) package with exposed pad. It functions within an industrial temperature range of -40°C to +105°C.

Digital To Analog Converters Feature Summary

Digital To Analog Converters Procurement Notes

This specific part number is obsolete and no longer in production. Verification of current availability should focus on the direct replacement DAC102S085CISD/NOPB. Buyers must confirm lead times and stock status through authorized distributors as original manufacturing has ceased.

Digital To Analog Converters Selection Notes

Designers should consider the DAC102S085CISD/NOPB as the primary alternative due to identical pinout and electrical specifications. Ensure that the target application requires the 10-WSON package dimensions. Verify that the system's serial communication protocol matches the supported SPI or DSP modes without additional level shifting requirements.

Digital To Analog Converters Part Context

The DAC102S085 belongs to the DAC102S085 family of dual 10-bit converters. This series is characterized by its cost-optimized design and minimal size. The component represents a transition period where National Semiconductor products were integrated into Texas Instruments' portfolio, often sharing datasheets and specifications under the TI brand.

Digital To Analog Converters Replacement Considerations

DAC102S085CISD/NOPB serves as the direct functional substitute. It maintains the same 10-bit resolution, dual-channel configuration, and WSON-10 packaging. No external component changes are required for migration.
