DAC128S085CIMTX

Digital To Analog Converters Overview

The DAC128S085CIMTX is an octal, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features rail-to-rail outputs and operates on a single supply voltage ranging from 2.7 V to 5.5 V for both analog and digital domains. The device supports serial interfaces including SPI, QSPI, Microwire, and DSP modes with clock rates up to 40 MHz. It utilizes a resistor string architecture and offers low power consumption of 1.95 mW per channel. The component is housed in a 16-pin TSSOP package and functions within a 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 buffered voltage outputs in a compact surface-mount package.
• Supports flexible high-speed serial communication through compatibility with standard SPI, QSPI, Microwire, and DSP interface protocols.
• Operates on a single power supply with wide voltage tolerance, enabling direct interfacing with various logic levels without external level shifting.

Digital To Analog Converters Applications

• Industrial process control systems requiring multiple analog output signals
• Portable battery-powered instrumentation due to micro-power characteristics
• Automated test equipment needing precise multi-channel voltage generation

Digital To Analog Converters Procurement Notes

Verify the specific suffix and manufacturer details against current official datasheets before integration, as component availability and revision status may vary. Confirm that the 16-TSSOP package dimensions align with your PCB footprint requirements. Ensure that the operating temperature range meets your environmental specifications. Check for any end-of-life notices or obsolescence warnings associated with this specific part number from the manufacturer.

Digital To Analog Converters Selection Notes

Select this component when eight independent 12-bit analog outputs are required in a space-constrained design. It is suitable for applications demanding low power consumption and high speed via serial interfaces. Consider alternative channel counts such as the dual or quad variants if fewer outputs suffice. Verify that the resistor string architecture and specified linearity errors meet your system accuracy requirements.

Digital To Analog Converters Part Context

This part belongs to the DAC128S085 family of micro-power octal DACs from Texas Instruments. It shares architectural similarities with other members like the DAC128S085CISQ but differs in packaging. The series is designed for cost-sensitive, high-density applications requiring multiple analog channels. Related parts include lower channel count variants and different package options within the same functional family.

Digital To Analog Converters Replacement Considerations

Direct substitutes include the DAC128S085CIMT/NOPB which shares identical electrical specifications but may differ in tape-and-reel packaging configuration. The DAC128S085CISQ offers the same functionality in a WQFN-16 package, requiring PCB layout adjustments. Verify pinout compatibility and thermal performance when swapping between TSSOP and QFN packages.
