MAX5802AAUB+T

Digital To Analog Converters Overview

The MAX5802AAUB+T is a dual-channel, 12-bit voltage-output digital-to-analog converter (DAC) featuring an internal selectable reference and I2C interface. It operates on a wide supply range of 2.7V to 5.5V with low power consumption. The device includes buffered outputs capable of driving 2kΩ loads directly, settling in 4.5µs. It supports separate 1.8V to 5.5V VDDIO logic levels and offers software-selectable power-down impedances.

Digital To Analog Converters Feature Summary

• Dual high-accuracy DAC channels with independent mode settings
• Internal precision reference selectable at 2.048V, 2.500V, or 4.096V
• Buffered voltage output with rail-to-rail operation capability
• Asynchronous clear input for zero-scale initialization

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific AA suffix against official documentation to confirm accuracy grade and temperature coefficient specifications. Ensure the T suffix indicates tape-and-reel packaging if required for automated assembly processes. Confirm availability status through authorized distributors as stock levels vary.

Digital To Analog Converters Selection Notes

Select this component when 12-bit resolution and dual-channel independence are required in a small footprint. The integrated buffer eliminates external op-amps, while the separate VDDIO pin allows compatibility with various logic families. Verify that the 4.5µs settling time meets system speed requirements.

Digital To Analog Converters Part Context

This part belongs to the MAX5800/MAX5801/MAX5802 family of ultra-small DACs. While sharing the same package and interface, the MAX5802 provides 12-bit resolution compared to the 8-bit MAX5800 and 10-bit MAX5801. All variants share identical pinouts and functional blocks.

Digital To Analog Converters Replacement Considerations

MAX5800BAUB+T: 8-bit resolution variant. MAX5801BAUB+T: 10-bit resolution variant. Cross-model substitution requires verification of resolution and linearity requirements.
