MAX5800AUB+T

Digital To Analog Converters Overview

The MAX5800AUB+T is a dual-channel, low-power digital-to-analog converter (DAC) featuring 12-bit resolution. It operates on a wide supply voltage range of 2.7V to 5.5V with typical power consumption of 1.5mW. The device includes buffered voltage outputs and selectable internal references of 2.048V, 2.500V, or 4.096V. Communication is handled via a fast 400kHz I2C-compatible serial interface. Key performance metrics include a settling time of 4.5µs for the 12-bit version, an offset error of ±5mV, and a gain error of ±1%FS. It supports asynchronous clearing and software-selectable power-down modes.

Digital To Analog Converters Feature Summary

• Dual high-accuracy DAC channels with independent mode settings
• Internal precision reference selectable between 2.048V, 2.500V, and 4.096V
• Rail-to-rail buffered voltage output capable of driving 2kΩ loads
• Asynchronous clear input for immediate zero-scale initialization

Digital To Analog Converters Applications

• Programmable voltage and current sources
• Gain and offset adjustment circuits
• Automatic tuning and optical control systems
• Power amplifier control and biasing
• Process control and servo loops

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'AUB+T' against the manufacturer's official documentation to confirm package type and tape-and-reel configuration. Ensure the component meets RoHS compliance standards as indicated by the '+' designation. Cross-reference the ordering information in the datasheet to validate availability and lead times through authorized distributors.

Digital To Analog Converters Selection Notes

Select this component when a compact dual-channel solution with integrated buffering is required. The separate VDDIO pin allows compatibility with 1.8V logic interfaces while maintaining a wider analog supply range. Consider the 4.5µs settling time and ±1 LSB INL for applications demanding precise signal generation without external calibration.

Digital To Analog Converters Part Context

This part belongs to the MAX5800/MAX5801/MAX5802 family of ultra-small DACs. The MAX5800 variant specifically provides 12-bit resolution, distinguishing it from the 8-bit MAX5800 and 10-bit MAX5801 options within the same series. All variants share identical pinouts and interface protocols.

Digital To Analog Converters Replacement Considerations

Direct replacements within the same family include the MAX5801AUB+T (10-bit) and MAX5802AUB+T (12-bit). Verify that the replacement matches the required resolution and package dimensions. No other cross-family substitutes are officially documented.
