MCP47FEB02A0T-E/ST

Digital To Analog Converters Overview

The MCP47FEB02A0T-E/ST is a dual-channel, 8-bit buffered voltage output Digital-to-Analog Converter (DAC) featuring nonvolatile EEPROM memory and an I²C serial interface. It operates within a supply voltage range of 1.8V to 5.5V, providing rail-to-rail analog outputs with a typical settling time of 6 µs. The device supports Standard (100 kbps), Fast (400 kbps), and High-Speed (up to 3.4 Mbps) communication modes. Key electrical parameters include a maximum gain error of ±1.0% FSR, integral nonlinearity (INL) of ±0.5 LSB, and differential nonlinearity (DNL) of ±0.25 LSB. Power consumption is typically less than 380 µA in normal operation and drops to 650 nA in power-down mode.

Digital To Analog Converters Feature Summary

• Dual-channel architecture with integrated nonvolatile EEPROM for persistent DAC register storage and configuration recall upon power-up or brown-out reset.
• Flexible reference input options allowing selection between the VDD pin, an external VREF pin, or an internal bandgap voltage source.
• Configurable output buffer gain settings of unity (1x) or two times (2x) when utilizing an external reference voltage.
• Robust protection features including power-on/brown-out reset logic and a dedicated nonvolatile memory write protect bit.

Digital To Analog Converters Applications

• Set point or offset trimming in precision circuits
• Sensor calibration systems
• Low-power portable instrumentation

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature grade. Ensure the component matches the required I²C address configuration and memory retention specifications for the target application environment.

Digital To Analog Converters Selection Notes

Select this component for designs requiring dual-channel analog output generation with data persistence without external memory chips. Consider the 8-bit resolution limits for linearity requirements and verify that the I²C bus speed requirements align with the supported Standard, Fast, or High-Speed modes.
