MCP4706A2T-E/MAY

Digital To Analog Converters Overview

The MCP4706A2T-E/MAY is a single-channel, 8-bit buffered voltage output Digital-to-Analog Converter (DAC) manufactured by Microchip Technology. It features an integrated nonvolatile EEPROM for retaining DAC register settings and configuration bits across power cycles. The device operates on a single supply voltage ranging from 2.7V to 5.5V and communicates via a two-wire I2C interface supporting Standard (100 kbps), Fast (400 kbps), and High-Speed (3.4 Mbps) modes. Key electrical parameters include a typical settling time of 6 µs, a maximum power consumption of 210 µA in normal operation, and an extended operating temperature range from -40°C to +125°C. It is housed in a compact 6-lead DFN (2x2 mm) package.

Digital To Analog Converters Feature Summary

• Integrates nonvolatile EEPROM to automatically recall saved DAC register values and device configuration upon power-up or reset events.
• Supports flexible reference voltage selection between the internal VDD rail and an external VREF pin, with configurable buffer gain options of 1x or 2x when using the external reference.
• Provides multiple low-power shutdown modes that disconnect the output buffer and allow selection of specific pull-down resistor values to minimize system current consumption.

Digital To Analog Converters Applications

• Set point or offset trimming in industrial control systems
• Sensor calibration circuits requiring persistent configuration data
• Low-power portable instrumentation devices
• Motor control applications needing precise voltage regulation

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'MAY' corresponds to the 6-lead DFN (2x2 mm) package variant rather than the SOT-23-6 option. Confirm that the A2 designation aligns with the required factory-set I2C slave address for your bus topology. Ensure the component meets RoHS compliance standards if mandated by your assembly specifications.

Digital To Analog Converters Selection Notes

Select this component when an 8-bit resolution is sufficient for the application's accuracy requirements. Choose this part over higher-resolution variants like the MCP4716 or MCP4726 if minimizing cost and power consumption is prioritized. Ensure the design accommodates the specific I2C address assigned to the 'A2' suffix to prevent bus conflicts with other devices.

Digital To Analog Converters Part Context

This device belongs to the MCP47X6 family, which includes 10-bit (MCP4716) and 12-bit (MCP4726) counterparts. All members share identical pinouts, interfaces, and functional blocks, differing primarily in resolution and associated accuracy metrics. The MCP4706 serves as the entry-level option within this series for cost-sensitive applications.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include MCP4706A0T-E/MAY and MCP4706A1T-E/MAY, which differ only in their pre-programmed I2C addresses. Cross-family replacements such as the MCP48 series require SPI interface compatibility checks and do not offer nonvolatile memory retention.
