MAX5800AUB+

Digital To Analog Converters Overview

The MAX5800AUB+ is a dual-channel, low-power digital-to-analog converter (DAC) featuring 8-bit resolution. It operates on a supply voltage range of 2.7V to 5.5V with a typical supply current of 350µA at 3V. The device includes buffered voltage outputs and an internal reference selectable to 2.048V, 2.500V, or 4.096V. It utilizes a fast 400kHz I2C-compatible serial interface and features a separate 1.8V to 5.5V VDDIO power-supply input. The unit provides a power-on-reset to zero-scale output and supports asynchronous clearing via a CLR logic input.

Digital To Analog Converters Feature Summary

• Gain and Offset Adjustment
• Automatic Tuning and Optical Control
• Power Amplifier Control and Biasing
• Process Control and Servo Loops

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'A' against official documentation to confirm temperature grade and performance specifications. Confirm package availability in the µMAX format. Ensure compatibility with existing system designs regarding the I2C address configuration and power supply requirements before finalizing procurement.

Digital To Analog Converters Selection Notes

Select this component when dual-channel conversion is required within a compact footprint. The 8-bit resolution suits applications where moderate accuracy is sufficient. Verify that the 2.7V to 5.5V supply range aligns with the target system architecture. Consider the separate VDDIO pin if interfacing with lower-voltage logic controllers.

Digital To Analog Converters Part Context

This part belongs to the MAX5800/MAX5801/MAX5802 family of ultra-small DACs. While sharing the same physical package and core architecture, the MAX5800 specifically offers 8-bit resolution, distinguishing it from the 10-bit MAX5801 and 12-bit MAX5802 variants. All members share identical pinouts and interface protocols.

Digital To Analog Converters Replacement Considerations

Direct replacements include the MAX5801AUB+ and MAX5802AUB+. These parts maintain the same package and interface but offer higher resolutions of 10-bit and 12-bit respectively. Verify if the increased resolution meets system requirements without affecting board layout.
