MCP47FEB22A3T-E/ST

Digital To Analog Converters Overview

The MCP47FEB22A3T-E/ST is a dual-channel, 12-bit buffered voltage output Digital-to-Analog Converter (DAC) with nonvolatile EEPROM memory and an I²C serial interface. It operates within a supply voltage range of 1.8V to 5.5V, supporting full specifications from 2.7V to 5.5V and reduced specifications from 1.8V to 2.7V. The device features rail-to-rail outputs, a typical settling time of 6 µs, and selectable reference sources including VDD, external VREF, or an internal 1.22V bandgap. It supports Standard (100 kbps), Fast (400 kbps), and High-Speed (up to 3.4 Mbps) I²C modes.

Digital To Analog Converters Feature Summary

• Dual-channel architecture with integrated nonvolatile EEPROM for power-on reset recall and configuration retention
• Configurable I²C interface supporting up to 3.4 Mbps communication speeds
• Flexible reference selection allowing use of internal bandgap, VDD, or external VREF pin
• Low-power operation with programmable power-down modes and high-voltage command capability

Digital To Analog Converters Applications

• Set point or offset trimming in precision circuits
• Sensor calibration systems requiring nonvolatile storage
• Low-power portable instrumentation
• Data acquisition systems
• Motor control applications

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'A3' against official Microchip documentation to confirm the programmed slave address and initial EEPROM state. Ensure the TSSOP-8 package variant matches the required PCB footprint. Confirm RoHS compliance status through the manufacturer's current product status page before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when dual independent analog outputs are required alongside persistent configuration data. The 12-bit resolution provides 4096 steps for precise voltage control. Consider the extended temperature range (-40°C to +125°C) for industrial environments. Verify that the I²C bus speed requirements align with the device's High-Speed mode capabilities.

Digital To Analog Converters Part Context

This part belongs to the MCP47FEBXX family of nonvolatile DACs. The '22' designation indicates a dual-channel configuration with 12-bit resolution. The 'E' suffix denotes the extended industrial temperature range. The 'T' indicates tape and reel packaging, while '/ST' specifies the TSSOP-8 package type.

Digital To Analog Converters Replacement Considerations

Direct substitutes include other MCP47FEB22 variants with different packaging or addressing suffixes. Single-channel equivalents like the MCP47FEB21 offer similar performance but with only one output. Cross-family comparisons should focus on resolution, channel count, and nonvolatile memory presence.
