DAC128S085CISQX

Digital To Analog Converters Overview

The DAC128S085CISQX is a micro-power, octal digital-to-analog converter featuring 12-bit resolution and eight independent channels. It utilizes a resistor string architecture with voltage-buffered outputs capable of rail-to-rail swing. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V for both analog and digital domains. Key electrical specifications include a settling time of 8.5 µs, a maximum power consumption of 1.95 mW, and an operating current of 650 µA. It supports serial interfaces including SPI, QSPI, Microwire, and DSP modes within a compact 16-pin WQFN package.

Digital To Analog Converters Feature Summary

• Integrates eight independent 12-bit DAC channels in a single compact package.
• Features voltage-buffered outputs that drive loads directly without external amplifiers.
• Supports multiple high-speed serial communication protocols for flexible system integration.
• Designed for low-power applications with micro-watt level standby capabilities.

Digital To Analog Converters Applications

• Portable instrumentation requiring multi-channel signal generation
• Battery-powered data acquisition systems
• Industrial process control loops
• Medical equipment signal conditioning

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'X' indicates reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation as required by regional regulations. Ensure the WQFN-16 footprint matches the PCB layout design. Validate that the external reference voltage range aligns with the 500 mV to 5.5 V specification before finalizing the bill of materials.

Digital To Analog Converters Selection Notes

Select this component when eight simultaneous 12-bit conversions are required in a space-constrained design. Compare against the DAC128S085CIMT if a TSSOP package is preferred over WQFN. Consider the DAC088S085 series if 8-bit resolution suffices for lower cost requirements. Verify that the 2.5 MS/s sampling rate meets the application bandwidth needs.

Digital To Analog Converters Part Context

This part belongs to the Texas Instruments DAC128S085 family of octal DACs. It shares architectural similarities with the DAC124S085 (quad channel) and DAC101C085 (single channel I2C). The device complements other data converters in the portfolio by offering high channel density and low power consumption for embedded systems.

Digital To Analog Converters Replacement Considerations

DAC128S085CISQ/NOPB is the non-reel variant of the same functional device. DAC128S085CIMT/NOPB offers identical performance in a TSSOP-16 package. DAC128S085EVM is an evaluation board, not a direct pin-for-pin replacement.
