DAC128S085CIMT/NOPB

Digital To Analog Converters Overview

The DAC128S085CIMT/NOPB is a 12-bit micro-power octal digital-to-analog converter manufactured by Texas Instruments. It integrates eight independent voltage-output DACs in a single package, featuring rail-to-rail outputs and a serial interface compatible with standard SPI, QSPI, Microwire, and DSP protocols. The device operates on a single analog supply voltage ranging from 2.7 V to 5.5 V and supports digital logic levels from 1.7 V to 5.5 V. Key performance metrics include a maximum sampling rate of 2.5 MS/s per channel, a typical settling time of 6 µs, and a power consumption of 1.95 mW. It is housed in a 16-pin TSSOP package and functions within an industrial temperature range of -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Integrates eight independent 12-bit DAC channels with rail-to-rail output capability for wide dynamic range signal generation.
• Supports high-speed serial communication via SPI, QSPI, Microwire, and DSP interfaces with data rates up to 40 MHz.
• Features low power consumption with a dedicated shutdown mode that significantly reduces current draw during idle periods.
• Includes a flexible external reference input allowing the full-scale output range to be scaled according to system requirements.

Digital To Analog Converters Applications

• Industrial process control systems requiring multiple simultaneous analog outputs.
• Portable instrumentation and battery-powered test equipment due to low power characteristics.
• Data acquisition systems utilizing multiplexed analog signal conditioning.
• Automotive sensor interface circuits operating in harsh thermal environments.

Digital To Analog Converters Procurement Notes

Verify the specific suffix against the manufacturer's latest documentation to ensure compatibility with required packaging formats and environmental certifications. Confirm that the selected variant matches the intended pinout and electrical specifications for the target application design.

Digital To Analog Converters Selection Notes

Select this component when multiple isolated analog outputs are needed without occupying excessive board space. Ensure the system clock frequency does not exceed the specified limit for the chosen serial interface mode. Verify that the external reference voltage source can drive the input pin adequately across the full operating temperature range.

Digital To Analog Converters Part Context

This part belongs to the DAC128S085 family of octal converters, which also includes variants like the DAC128S085CIMTX/NOPB differing primarily in reel packaging. It shares architectural similarities with dual-channel counterparts such as the DAC122S085 but offers higher channel density for multi-signal applications.

Digital To Analog Converters Replacement Considerations

The DAC128S085CIMTX/NOPB serves as a direct functional substitute with identical electrical characteristics, differing only in tape-and-reel packaging configuration. Other family members may require pinout or interface adjustments.
