DAC7558IRHBR

Digital To Analog Converters Overview

The DAC7558IRHBR is a 12-bit octal digital-to-analog converter manufactured by Texas Instruments. It integrates eight independent voltage-output channels within a single package, offering high channel density for space-constrained designs. The device operates with a supply voltage range of 2.7 V to 5.5 V and supports serial interfaces including SPI and Microwire. Key electrical characteristics include an ultralow glitch impulse of 0.1 nV-sec and a settling time of 3 microseconds. It functions across an industrial temperature range from -40°C to +85°C and is housed in a 48-pin TSSOP package.

Digital To Analog Converters Feature Summary

• Integrates eight independent 12-bit DAC channels for multi-channel signal generation
• Features ultralow glitch impulse performance to minimize output transients during code transitions
• Supports standard serial communication protocols including SPI and Microwire for flexible system integration
• Provides rail-to-rail voltage outputs compatible with various analog loads

Digital To Analog Converters Applications

• Industrial process control systems requiring multiple analog outputs
• Programmable power supplies and battery test equipment
• Data acquisition systems with multi-channel signal conditioning
• Medical instrumentation requiring precise analog waveform generation

Digital To Analog Converters Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm package type and temperature grade. Ensure compatibility with existing serial interface configurations on the target PCB. Check for RoHS compliance status if required by regional regulations. Confirm availability through authorized distributors to avoid counterfeit components.

Digital To Analog Converters Selection Notes

Select this component when eight independent 12-bit voltage outputs are required in a compact form factor. Compare against the DAC7554 or DAC7552 if fewer channels suffice to reduce cost. Consider the DAC8554 series if higher 16-bit resolution is necessary for precision applications. Evaluate power consumption requirements against the specified operating current ranges.

Digital To Analog Converters Part Context

This part belongs to the DAC755x family of ultralow glitch digital-to-analog converters. It serves as the octal variant within a lineup that includes dual (DAC7552), quad (DAC7554), and single-channel (DAC7551) options. The family shares common architectural features such as ultralow glitch impulses and serial interface compatibility, allowing for scalable design architectures across different channel count requirements.

Digital To Analog Converters Replacement Considerations

The DAC7558IRHBT is the tape-and-reel alternative to the reel-packaged IRHBR version. For reduced channel counts, the DAC7554 offers quad-channel functionality with identical performance characteristics. Higher resolution needs may require upgrading to the 16-bit DAC8554 series.
