MCP48FEB14T-E/MQ

Digital To Analog Converters Overview

The MCP48FEB14T-E/MQ is a quad-channel, 10-bit voltage output Digital-to-Analog Converter (DAC) from Microchip Technology. It features nonvolatile EEPROM memory for data retention and operates within an extended temperature range of -40°C to +125°C. The device supports supply voltages from 2.7V to 5.5V, with reduced specifications available between 1.8V and 2.7V. It utilizes an SPI interface supporting up to 20 MHz writes and 10 MHz reads. Key electrical parameters include a typical settling time of 7.8 µs, rail-to-rail buffered outputs, and power-down current as low as 680 nA.

Digital To Analog Converters Feature Summary

• Integrated nonvolatile EEPROM memory enables auto-recall of DAC register settings and device configuration upon power-up or brown-out reset events.
• WiperLock™ functionality prevents inadvertent changes to stored output values using high-voltage commands on dedicated latch pins.
• Flexible reference input options allow selection between external VREF pin, internal band gap voltage source, or device VDD.
• Configurable gain settings and power-down modes provide control over output buffer state and pull-down resistor selection.

Digital To Analog Converters Applications

• Set point or offset trimming in industrial systems
• Sensor calibration requiring persistent configuration storage
• Low-power portable instrumentation
• Data acquisition systems

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 compatibility with system voltage levels and SPI timing requirements before integration. Cross-reference the datasheet revision to confirm all electrical characteristics match design specifications.

Digital To Analog Converters Selection Notes

Select this component when multiple analog channels are required with nonvolatile memory capabilities. Compare volatile RAM versions if power consumption during active operation is critical and data persistence is not needed. Verify that the 10-bit resolution meets the application's accuracy requirements relative to the selected reference voltage.

Digital To Analog Converters Part Context

This part belongs to the MCP48FXBX4/8 family, which includes quad and octal configurations with varying resolutions. The 'E' suffix indicates the extended temperature range, while 'MQ' specifies the 20-lead VQFN package. Other variants in the series offer different bit depths and memory types to suit diverse design constraints.

Digital To Analog Converters Replacement Considerations

The MCP48FVB14T-E/MQ serves as a direct substitute if nonvolatile memory is unnecessary. For applications requiring higher resolution, consider the MCP48FEB24T-E/MQ. Octal channel requirements may necessitate the MCP48FEB18T-E/MQ variant.
