MAX5805AAUB+T

Digital To Analog Converters Overview

The MAX5805AAUB+T is a single-channel, 12-bit buffered output voltage digital-to-analog converter (DAC) from the MAX5803/MAX5804/MAX5805 family. It features an internal selectable reference of 2.048V, 2.500V, or 4.096V and operates on a wide supply voltage range of 2.7V to 5.5V with power consumption under 1mW. The device utilizes a fast 400kHz I2C-compatible serial interface and includes a user-configurable asynchronous AUX input for CLR or GATE functions. It guarantees monotonicity without adjustments, offers ±1 LSB INL, and provides a 6.3µs settling time. The component is housed in a compact 10-pin µMAX package and is specified over an extended temperature range of -40°C to +125°C.

Digital To Analog Converters Procurement Notes

Verify the specific 'A' suffix designation against official documentation to confirm accuracy grade specifications. Confirm the 'T' tape-and-reel packaging format matches design requirements. Ensure the manufacturer source is recognized as Analog Devices Inc. or Maxim Integrated. Validate RoHS compliance status through current datasheet revisions before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when a single-channel, high-resolution 12-bit DAC is required in an ultra-small footprint. The MAX5805AAUB+T is suitable for low-voltage applications due to its wide 2.7V to 5.5V supply range and sub-milliwatt power consumption. Consider the integrated buffer and selectable internal references to simplify external circuitry design.

Digital To Analog Converters Part Context

The MAX5805AAUB+T belongs to the MAX5803/MAX5804/MAX5805 series of ultra-small, single-channel DACs. This family shares identical pinouts and functional architectures, differing primarily in resolution: 8-bit for MAX5803, 10-bit for MAX5804, and 12-bit for MAX5805. All variants utilize the same 10-pin TDFN/µMAX packages and support the same I2C interface protocols.

Digital To Analog Converters Replacement Considerations

Direct replacements within the same family include the MAX5803AUB+T (8-bit) and MAX5804AUB+T (10-bit), which share identical pinouts and interfaces but offer lower resolution. Cross-family alternatives require verification of pin compatibility and electrical parameter alignment.
