MCP48FEB21-E/UN

Digital To Analog Converters Overview

The MCP48FEB21-E/UN is a single-channel, 12-bit buffered voltage output Digital-to-Analog Converter (DAC) featuring nonvolatile EEPROM memory and an SPI-compatible serial interface. It operates within a supply voltage range of 2.7V to 5.5V for full specifications, with reduced specifications available from 1.8V to 2.7V. The device provides rail-to-rail output capability and supports reference sources including the internal bandgap (1.22V typical), external VREF pin, or device VDD. Key electrical parameters include a typical settling time of 7.8 µs, normal operation current of less than 180 µA at 1 MHz, and power-down current of 650 nA typical. It is housed in a 10-lead MSOP package and functions across an extended temperature range of -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Integrated nonvolatile EEPROM memory enables user-programmable Power-on Reset (POR) and Brown-out Reset (BOR) output settings, along with auto-recall of saved DAC register values and device configuration bits such as voltage reference and gain.
• Flexible DAC voltage reference source options allow selection between the device VDD, an external VREF pin (configurable as buffered or unbuffered), or an internal bandgap voltage.
• Configurable output gain options provide unity (1x) or 2x amplification when using an external reference, supporting rail-to-rail output swing capabilities.

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 that the specific ordering suffix matches the required package type and temperature grade. Confirm that the design accommodates the extended temperature range requirements if operating outside standard industrial limits. Ensure the system power supply remains within the specified voltage thresholds to maintain full analog performance specifications.

Digital To Analog Converters Selection Notes

Select this component when a single-channel DAC with nonvolatile memory retention is required. Consider the 12-bit resolution and fast settling time for applications demanding precise analog control. Evaluate the low power consumption characteristics against battery-operated constraints. Verify compatibility with the host microcontroller's SPI interface modes.

Digital To Analog Converters Part Context
