MCP47FEB18-E/MQ

Digital To Analog Converters Overview

The MCP47FEB18-E/MQ is a quad-channel, 10-bit Digital-to-Analog Converter (DAC) from the MCP47FXBX4/8 family. It features nonvolatile EEPROM memory for data retention and an I2C interface. The device operates with supply voltages ranging from 1.8V to 5.5V, supporting full specifications at 2.7V-5.5V and reduced specifications at 1.8V-2.7V. Key electrical parameters include a typical settling time of 7.8 µs, a gain error of ±1.0% FSR, and integral nonlinearity (INL) of ±1.5 LSB. It utilizes rail-to-rail buffered voltage outputs and supports Standard (100 kbps), Fast (400 kbps), and High-Speed (up to 3.4 Mbps) I2C modes.

Digital To Analog Converters Feature Summary

• Integrates nonvolatile EEPROM memory to automatically recall DAC register settings and device configuration upon power-up or brown-out reset events.
• Features WiperLock™ technology that prevents inadvertent changes to output values using high-voltage commands on dedicated pins.
• Provides flexible voltage reference options including external VREF pin, internal band gap, or device VDD, with selectable gain configurations.

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature range. Ensure the selected variant matches the required channel count and memory type for the design. Cross-reference datasheet revision numbers to guarantee compatibility with existing firmware and hardware schematics.

Digital To Analog Converters Selection Notes

Select this component when a quad-channel solution with persistent storage is required. The 10-bit resolution offers a balance between precision and speed. Consider the operating voltage range; full specifications apply above 2.7V, while lower voltages may require checking reduced analog performance limits in the datasheet.

Digital To Analog Converters Part Context

This part belongs to the MCP47FXBX4/8 family, which includes octal variants and different resolution options (8-bit, 10-bit, 12-bit). The 'E' indicates extended temperature range (-40°C to +125°C), and 'MQ' denotes the 20-lead VQFN package. It shares the same core architecture as volatile RAM versions but adds EEPROM for nonvolatile operation.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include MCP47FVB18-E/MQ (volatile RAM version) or MCP47FEB18-E/ST (TSSOP package). For octal channel requirements, consider MCP47FEB18-E/MQ. Verify pinout compatibility and memory type differences before substitution.
