MCP48CMB24-E/ML

Overview

The MCP48CMB24-E/ML is a quad-channel, 12-bit Digital-to-Analog Converter (DAC) featuring Multi-Time Programmable (MTP) nonvolatile memory. It operates within a supply voltage range of 2.7V to 5.5V and utilizes an SPI serial interface with write speeds up to 50 MHz. The device provides buffered voltage outputs with selectable gain options of 1x or 2x. Reference sources include VDD, an external VREF pin, or an internal band gap. It includes power-on/brown-out reset protection and configurable power-down modes. The component is housed in a 20-lead QFN package and supports an extended temperature range from -40°C to +125°C.

Feature Summary

• Integrates MTP nonvolatile memory for retaining output values and configuration data across power cycles.
• Offers flexible reference voltage selection between device supply, external pins, and an internal band gap source.
• Supports high-speed SPI communication with programmable gain settings for the analog output stage.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature grade. Ensure the design accommodates the required programming voltage on the HVC pin if MTP writing is utilized. Confirm that the system logic levels are compatible with the specified SPI interface thresholds before integration.

Selection Notes

Select this model when four independent 12-bit channels with persistent storage are required. Compare against volatile variants if power retention is unnecessary. Verify that the 20-lead QFN footprint fits the PCB layout constraints. Check that the application does not exceed the maximum current sourcing or sinking limits of the output buffers.

Part Context

This component belongs to the MCP48CXBX4/8 family of digital-to-analog converters. It shares architectural similarities with other members regarding the SPI interface and core DAC structure. Distinctive features include the specific 12-bit resolution and the inclusion of nonvolatile MTP memory, differentiating it from volatile RAM-based counterparts in the same series.
