MCP4706A0T-E/MAY

Digital To Analog Converters Overview

The MCP4706A0T-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 and 60 nA in power-down mode. It offers rail-to-rail output with a typical settling time of 6 µs. The component supports Standard (100 kbps), Fast (400 kbps), and High-Speed (3.4 Mbps) I2C modes. It is available in a compact 6-lead DFN (2x2 mm) package and functions within an extended temperature range of -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Integrated nonvolatile EEPROM retains DAC register settings and configuration bits across power cycles.
• Configurable power-down modes allow selection of VOUT pull-down resistors or buffer disconnection to minimize current consumption.
• Dual reference voltage options enable use of either the internal VDD or an external VREF pin as the voltage reference source.

Digital To Analog Converters Applications

• Set point or offset trimming in industrial control systems
• Sensor calibration circuits requiring precise analog outputs
• Low-power portable instrumentation devices
• PC peripherals and data acquisition systems

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and tape-and-reel specifications. Ensure that the selected variant matches the required thermal pad exposure and lead finish standards for your assembly process. Cross-reference the datasheet revision date to confirm compliance with current RoHS and REACH directives before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when an 8-bit resolution is sufficient for the application requirements. Consider the MCP4716 or MCP4726 if higher resolution (10-bit or 12-bit) is necessary. Evaluate the need for external versus internal voltage references based on system accuracy requirements. Confirm that the I2C bus speed capabilities align with the master controller's performance limits.

Digital To Analog Converters Part Context

This part belongs to the MCP47X6 family of single-channel DACs, which also includes the MCP4716 and MCP4726 models. These devices share identical pinouts and functional architectures but differ primarily in resolution and associated electrical characteristics. The family is designed for applications requiring small footprints and low power consumption while maintaining nonvolatile data storage capabilities.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include the MCP4716 and MCP4726, provided the application can accommodate their respective resolutions. Verify pin compatibility and software register mapping when switching between these variants. No other cross-manufacturer replacements are confirmed in the public documentation.

Digital To Analog Converters FAQ

What happens to the DAC output value during a power cycle?

The DAC register value stored in the nonvolatile EEPROM is automatically recalled and loaded into the volatile DAC register upon power-up, ensuring the output maintains its previous state.

Can the output gain be adjusted?

Yes, when using an external VREF pin, the output buffer gain can be configured to unity (1x) or doubled (2x). If VDD is used as the reference, the gain remains at unity.

How does the device handle power-down states?

The device offers multiple power-down modes via the PD1:PD0 bits, allowing the user to disconnect the output buffer or select specific internal pull-down resistor values (640 kΩ, 125 kΩ, or 1 kΩ) to reduce current consumption.
