MAX5805BATB+T

Digital To Analog Converters Overview

The MAX5805BATB+T is a single-channel, 12-bit buffered output voltage digital-to-analog converter (DAC) from Analog Devices/Maxim Integrated. It features an internal selectable reference of 2.048V, 2.500V, or 4.096V and operates on a wide supply range of 2.7V to 5.5V with power consumption under 1mW. The device utilizes a fast 400kHz I2C-compatible 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 TDFN package.

Verify the specific ordering suffix BATB against official documentation to confirm the exact package type and tape-and-reel configuration. Ensure compatibility with the required operating temperature range and supply voltage specifications before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when a high-accuracy 12-bit resolution is required alongside minimal board space constraints. The integrated buffer simplifies design by eliminating external amplifiers, while the low power consumption makes it suitable for battery-operated portable instrumentation applications.

Digital To Analog Converters Part Context

This part belongs to the MAX5803/MAX5804/MAX5805 family of ultra-small DACs. While sharing the same interface and core architecture, the MAX5805 specifically provides 12-bit resolution compared to the 8-bit and 10-bit variants, offering higher precision for demanding signal generation tasks.

Digital To Analog Converters Replacement Considerations

Direct functional replacements within the same series include the MAX5803AUB+ and MAX5804AUB+. Verify that the lower resolution of these alternatives meets the system requirements before substitution.

Digital To Analog Converters FAQ

What are the available internal reference voltage options?

The internal reference can be software-selected to provide 2.048V, 2.500V, or 4.096V.

How does the AUX pin function?

The AUX pin is an active-low asynchronous input that can be programmed to clear the DAC registers or gate the output to a user-programmable value.

Is the DAC output guaranteed to be monotonic?

Yes, the MAX5805 is guaranteed to be monotonic over all operating conditions without requiring external adjustments.
