MCP47FEB04T-20E/ST

Digital To Analog Converters Overview

The MCP47FEB04T-20E/ST is a quad-channel, 10-bit nonvolatile Digital-to-Analog Converter (DAC) from Microchip Technology. It features an I²C interface supporting Standard (100 kbps), Fast (400 kbps), and High-Speed (up to 3.4 Mbps) modes. The device operates on a supply voltage of 2.7V to 5.5V for full specifications, with reduced analog performance at 1.8V to 2.7V. It includes rail-to-rail buffered outputs, a typical settling time of 7.8 µs, and EEPROM memory for power-on reset settings. The component is housed in a 20-lead TSSOP package and supports an extended operating temperature range of -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Nonvolatile EEPROM storage retains DAC output values and configuration bits across power cycles.
• WiperLock™ technology prevents inadvertent changes to stored output values using high-voltage commands.
• Flexible reference input options include internal band gap, external VREF pin, or device VDD.
• Integrated power-on and brown-out reset protection ensures reliable startup states.

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against official datasheets to confirm package type and temperature grade. Ensure the selected variant matches the required channel count and resolution. Cross-reference the manufacturer part number with authorized distributors to confirm current availability and compliance status before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this model when four independent voltage outputs are required with persistent data retention. The 10-bit resolution provides 1024 steps suitable for moderate precision applications. Consider the I²C addressability and bus speed requirements relative to the host controller capabilities. Evaluate the power consumption profiles against system battery life constraints.

Digital To Analog Converters Part Context

This component belongs to the MCP47FXBX4/8 family of multi-channel DACs. It shares the same analog architecture and pinout as volatile RAM versions (MCP47FVBx) but utilizes EEPROM for data persistence. The '04' designation indicates a quad-channel configuration within the broader series that also includes octal variants.

Digital To Analog Converters Replacement Considerations

Direct functional replacements within the same family include other MCP47FEB04 variants with different packaging or suffixes. Volatile equivalents like the MCP47FVB04 offer identical electrical performance without nonvolatile storage. Verify pin compatibility and software register mapping when substituting with related models.
