MCP4706A3T-E/MAY

Digital To Analog Converters Overview

The MCP4706A3T-E/MAY is an 8-bit buffered voltage output Digital-to-Analog Converter (DAC) manufactured by Microchip Technology. It features a single channel with I2C serial interface and nonvolatile EEPROM memory for data retention. The device operates on a single supply voltage ranging from 2.7V to 5.5V, consuming 210 µA in normal operation. It supports Standard (100 kbps), Fast (400 kbps), and High-Speed (3.4 Mbps) communication modes. The component is housed in a compact 6-lead DFN (2x2 mm) package and functions reliably across an extended temperature range of -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Integrated nonvolatile EEPROM allows automatic recall of DAC register settings and device configuration upon power-up.
• Configurable output buffer gain options include unity (1x) and 2x when using the external VREF pin as the voltage source.
• Multiple power-down modes enable system current reduction by disconnecting the output buffer and selecting specific pull-down resistors.

Digital To Analog Converters Applications

• Set point or offset trimming
• Sensor calibration
• Low-power portable instrumentation

Digital To Analog Converters Procurement Notes

Verify the ordering suffix 'MAY' corresponds to the 6-lead DFN (2x2 mm) package type rather than the SOT-23 variant. Confirm that the 'A3' designation aligns with the required automotive qualification standards if applicable to the target design environment.

Digital To Analog Converters Selection Notes

Select this component when an 8-bit resolution is sufficient for the application requirements. Ensure the design accommodates the 2x7mm DFN footprint and thermal pad connection. Verify that the I2C bus speed requirements are compatible with the supported Standard, Fast, and High-Speed modes.

Digital To Analog Converters Part Context

This part belongs to the MCP47X6 family, which includes 10-bit (MCP4716) and 12-bit (MCP4726) variants. All members share identical pinouts, interfaces, and core functionalities, differing primarily in resolution and associated accuracy specifications such as INL and DNL errors.

Digital To Analog Converters Replacement Considerations

Direct functional replacements within the same family include MCP4706A1T-E/MAY and MCP4706A2T-E/MAY. These parts maintain the same package and electrical characteristics but may differ in factory pre-programmed values or specific qualification grades.
