DAC088S085CISQX/NOPB

Digital To Analog Converters Overview

The DAC088S085CISQX/NOPB is an octal digital-to-analog converter manufactured by Texas Instruments. It features eight independent channels with 8-bit resolution and a sampling rate of 220 kS/s. The device utilizes a serial interface compatible with SPI, QSPI, Microwire, DSP, and 3-Wire protocols. It operates on a single power supply ranging from 2.7 V to 5.5 V for both analog and digital domains. Key performance metrics include a settling time of 4.5 µs, differential nonlinearity (DNL) of 0.03 LSB, and integral nonlinearity (INL) of ±0.12 LSB. The output type is voltage buffered, and the unit is housed in a 16-WQFN package.

Digital To Analog Converters Feature Summary

• Octal architecture providing eight independent DAC channels within a single compact package.
• Voltage buffered outputs designed to drive loads directly without external amplification.
• Flexible serial interface supporting multiple standard communication protocols including SPI and Microwire.
• Micro-power consumption characteristics optimized for battery-operated applications.

Digital To Analog Converters Applications

• Portable instrumentation requiring multi-channel signal generation
• Battery-powered data acquisition systems
• Industrial process control loops
• Programmable gain amplifier offset adjustment

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'SQX' against the manufacturer's official documentation to confirm the tape-and-reel packaging configuration and pinout compatibility. Ensure that the operating voltage range aligns with the system's power supply rails before integration. Cross-reference the RoHS compliance status with current regulatory requirements for the target market.

Digital To Analog Converters Selection Notes

Select this component when eight low-resolution channels are required in a space-constrained design. Compare the 8-bit resolution against higher-precision alternatives like the DAC108S085 or DAC128S085 if greater accuracy is needed. Evaluate the 220 kS/s speed against application bandwidth requirements to ensure sufficient update rates for dynamic signals.

Digital To Analog Converters Part Context

This part belongs to the DAC088S085 family of micro-power octal DACs. It shares architectural similarities with the DAC108S085 and DAC128S085 series, differing primarily in resolution. The family is characterized by small footprint packages and low power consumption, targeting portable and industrial applications where channel count and size are critical constraints.

Digital To Analog Converters Replacement Considerations

Direct functional substitutes within the same family include DAC088S085CIMTX/NOPB and DAC088S085CIMT/NOPB, which offer identical electrical specifications but differ in packaging style. Verify pin compatibility when switching between WQFN and TSSOP packages.
