MCP48FEB01-E/UN

Digital To Analog Converters Overview

The MCP48FEB01-E/UN is a single-channel, 8-bit buffered voltage output Digital-to-Analog Converter (DAC) featuring nonvolatile EEPROM memory and an SPI serial interface. It operates within a supply voltage range of 1.8V to 5.5V, with full specifications guaranteed from 2.7V to 5.5V. The device provides rail-to-rail output capability and achieves a typical settling time of 7.8 µs. Reference options include the device VDD, an external VREF pin, or an internal 1.22V band gap. It supports unity (1x) or double (2x) output gain configurations.

Digital To Analog Converters Feature Summary

• Integrated EEPROM for nonvolatile storage of DAC register settings, device configuration bits, and power-on reset outputs.
• Flexible reference selection allowing operation with VDD, external VREF, or internal band gap sources.
• SPI-compatible serial interface supporting write speeds up to 20 MHz and read speeds up to 10 MHz.
• Configurable power-down modes that disconnect the output buffer or select specific pull-down resistor values.

Digital To Analog Converters Applications

• Set point or offset trimming in industrial systems
• Sensor calibration circuits
• Low-power portable instrumentation
• PC peripherals requiring analog signal generation

Digital To Analog Converters Procurement Notes

Verify the complete part number including the -E/UN suffix to ensure compliance with extended temperature ranges (-40°C to +125°C) and the MSOP-10 package type. Confirm that the design requires the specific 8-bit resolution and single-channel architecture defined for this model before ordering.

Digital To Analog Converters Selection Notes

Select this component when a single-channel DAC with persistent state retention is required. Ensure the application voltage does not exceed 5.5V and consider the 7.8 µs settling time against system speed requirements. Verify compatibility with the host controller's SPI mode support for '00' and '11' configurations.

Digital To Analog Converters Part Context

This device belongs to the MCP48FEBXX family of nonvolatile DACs manufactured by Microchip Technology. It shares architectural similarities with volatile RAM-based variants like the MCP47FVB series but distinguishes itself through integrated EEPROM for data retention without external backup power.

Digital To Analog Converters Replacement Considerations

Direct functional replacements within the same family include the MCP48FEB11-E/UN (10-bit) and MCP48FEB21-E/UN (12-bit), provided higher resolution is acceptable. For dual-channel applications, the MCP48FEB02-E/UN offers identical specifications across two channels.
