DAC128S085CIMT

Digital To Analog Converters Overview

The DAC128S085CIMT is an octal, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features a resistor-string architecture with eight independent voltage-output channels in a 16-pin TSSOP package. The device supports serial interfaces including SPI, QSPI, Microwire, and DSP modes. It operates on a single supply voltage ranging from 2.7 V to 5.5 V for analog power and 1.7 V to 5.5 V for digital I/O. Key electrical parameters include a maximum gain error of 1% FSR, a typical power consumption of 1.95 mW, and a settling time of 8.5 µs. The component functions within an industrial temperature range of -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Octal configuration providing eight independent 12-bit DAC channels in a compact surface-mount package.
• Flexible serial interface compatibility supporting standard SPI, QSPI, Microwire, and DSP protocols.
• Low-power design optimized for battery-operated systems with micro-watt power consumption levels.
• Rail-to-rail output capability allowing full-scale signal swing across the operating voltage range.

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel analog signal generation
• Portable instrumentation and data acquisition equipment
• Automotive sensor interface circuits

Digital To Analog Converters Procurement Notes

Verify the specific suffix against manufacturer documentation to confirm pinout and electrical characteristics match the required application. Ensure the ordering code corresponds to the TSSOP-16 package variant. Confirm RoHS compliance status through official datasheets prior to integration into production assemblies.

Digital To Analog Converters Selection Notes

Select this component when multiple low-cost, 12-bit analog outputs are needed within space-constrained designs. The wide digital supply range facilitates direct interfacing with various logic families without level shifting. Consider the 8.5 µs settling time for applications requiring moderate update rates rather than high-speed waveform generation.

Digital To Analog Converters Part Context

This part belongs to the DAC128S085 family of octal DACs. Variants such as the CIMTX and CISQ offer different packaging options like tape-and-reel or WQFN formats while maintaining identical core functionality. The CIMT designation specifically identifies the TSSOP-16 surface-mount package version suitable for general-purpose PCB layouts.

Digital To Analog Converters Replacement Considerations

Direct functional substitutes within the same family include the DAC128S085CIMTX/NOPB and DAC128S085CISQ. Verify package dimensions and thermal performance when swapping between TSSOP and WQFN variants to ensure mechanical fit.
