MAX5802BATB+T

Digital To Analog Converters Overview

The MAX5802BATB+T is a dual-channel, 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices/Maxim Integrated. It features buffered outputs and an internal reference selectable to 2.048V, 2.500V, or 4.096V. The device operates on a wide supply range of 2.7V to 5.5V with low power consumption. It utilizes a fast 400kHz I2C-compatible interface and includes a separate 1.8V to 5.5V VDDIO input. Key electrical parameters include a settling time of 4.5µs, ±1 LSB INL, and ±0.2 LSB DNL. It is housed in a 10-pin TDFN package and specified over the -40°C to +125°C temperature range.

Digital To Analog Converters Feature Summary

• Dual high-accuracy DAC channels with independent mode settings
• Internal precision selectable references for simplified design
• Buffered rail-to-rail voltage output capability
• Asynchronous clear input for immediate zero-scale reset

Digital To Analog Converters Applications

• Programmable Voltage and Current Sources
• 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 ordering suffix BATB+T against official manufacturer documentation to confirm the exact package type and tape-and-reel configuration. Ensure compatibility with the required operating temperature range and verify that the selected internal reference voltage meets system accuracy requirements before finalizing procurement.

Digital To Analog Converters Selection Notes

Select this component when a compact dual-channel solution with integrated buffering and reference is required. The 12-bit resolution and low nonlinearity make it suitable for precision applications. Consider the separate VDDIO pin for level shifting if the host processor operates at a different logic voltage than the analog supply.

Digital To Analog Converters Part Context

This part belongs to the MAX5800/MAX5801/MAX5802 family of ultra-small, dual-channel DACs. While sharing the same core architecture and interface, the MAX5802 specifically provides 12-bit resolution, distinguishing it from the 8-bit MAX5800 and 10-bit MAX5801 variants within the series.

Digital To Analog Converters Replacement Considerations

Direct functional substitutes within the same family include the MAX5800BAUB+T and MAX5801BAUB+T, which offer lower resolutions but share identical pinouts and interfaces. Verify that the reduced bit depth of these alternatives meets the specific accuracy requirements of the application.
