DAC088S085CIMT

Digital To Analog Converters Overview

The DAC088S085CIMT 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 operates on a single supply voltage ranging from 2.7 V to 5.5 V for both analog and digital domains. It utilizes a serial interface compatible with SPI, QSPI, Microwire, and DSP standards. Key performance metrics include a settling time of 4.5 µs, a power consumption of 1.95 mW, and a gain error of 1% FSR. Nonlinearity specifications are defined by a DNL of 0.03 LSB and an INL of +/- 0.12 LSB. The component is housed in a 16-pin TSSOP package.

Digital To Analog Converters Feature Summary

• Integrates eight independent 8-bit DAC channels within a compact surface-mount package.
• Supports multiple serial communication protocols including SPI, QSPI, and Microwire.
• Provides buffered voltage outputs suitable for driving various loads directly.

Digital To Analog Converters Applications

• Battery-powered instrumentation systems requiring low power consumption.
• Industrial process control loops utilizing serial microcontroller interfaces.
• Portable data acquisition devices needing multi-channel signal generation.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct packaging configuration. The base model designation may correspond to tube packaging, while suffix variations often indicate reel or cut tape options. Confirm RoHS compliance status and lead times through authorized distribution channels prior to procurement planning.

Digital To Analog Converters Selection Notes

Select this component when designing systems requiring eight simultaneous analog outputs with moderate precision. Ensure the host processor supports the required serial clock rates and protocol formats. Verify that the system power supply remains within the 2.7 V to 5.5 V operating range to maintain specified linearity and settling time performance across the industrial temperature range.

Digital To Analog Converters Part Context

This part belongs to the DAC088S085 series, which provides cost-effective solutions for multi-channel conversion tasks. It shares architectural similarities with other members like the DAC128S085 but offers lower resolution at reduced power levels. The TSSOP-16 footprint allows for space-constrained PCB layouts compared to larger packages used in higher channel count devices.

Digital To Analog Converters Replacement Considerations

The DAC088S085CIMTX/NOPB serves as a functional substitute differing primarily in shipping packaging format rather than electrical characteristics. Both variants share identical pinouts and performance specifications. Designers should verify that the alternative packaging aligns with automated assembly requirements without modifying the circuit schematic.
