DAC088S085CIMTX

Digital To Analog Converters Overview

The DAC088S085CIMTX is an octal digital-to-analog converter manufactured by Texas Instruments, featuring eight independent channels within a single integrated circuit. It provides 8-bit resolution with a sampling rate of 220 kS/s and a settling time of 4.5 ns. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V for both analog and digital domains. It utilizes buffered voltage outputs and supports serial interfaces including SPI, QSPI, Microwire, DSP, and 3-Wire protocols. Key performance metrics include a differential nonlinearity (DNL) of 0.03 LSB, integral nonlinearity (INL) of +/- 0.12 LSB, and a gain error of 1% FSR. Power consumption is specified at 1.95 mW, and it functions within a temperature range of -40°C to +125°C in a TSSOP-16 package.

Digital To Analog Converters Feature Summary

• Integrates eight independent 8-bit DACs into a compact surface-mount package to minimize board space.
• Supports multiple high-speed serial communication standards including SPI, QSPI, Microwire, and DSP interfaces.
• Features low power consumption suitable for battery-operated systems while maintaining fast settling times.

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific suffix against official documentation to confirm packaging type and environmental compliance. The 'CIMTX' designation indicates a TSSOP-16 package with tape-and-reel shipping. Confirm that the operating voltage requirements align with the system's power rails before integration. Ensure ESD protection measures are implemented during handling due to the sensitive CMOS input structure.

Digital To Analog Converters Selection Notes

Select this component when eight separate analog outputs are required from a single controller interface. It is appropriate for designs where board area is constrained but moderate resolution is sufficient. Compare DNL and INL specifications against application tolerance levels. Verify that the serial interface timing matches the microcontroller or DSP capabilities available in the design.

Digital To Analog Converters Part Context

This part belongs to the DAC088S085 family of octal DACs from Texas Instruments. It shares architectural similarities with other members like the DAC128S085 but offers lower 8-bit resolution compared to 12-bit variants. The device is designed to replace older discrete solutions or parallel DAC arrays in cost-sensitive applications.

Digital To Analog Converters Replacement Considerations

The DAC088S085CIMT/NOPB is a tube-packaged equivalent of the same functional device. For higher resolution needs, the DAC128S085 series serves as a pin-compatible upgrade path. Check datasheets for any changes in settling time or power consumption when substituting across the family.
