MCP48CMB21-E/MG

Overview

The MCP48CMB21-E/MG is a single-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 supports an SPI serial interface with write speeds up to 50 MHz. The device provides buffered voltage outputs with a typical settling time of 16 µs. It includes an internal 1.214V band gap reference or allows external VREF selection. The component is housed in a 10-lead MSOP package and functions across an extended temperature range from -40°C to +125°C.

Feature Summary

Integrates MTP memory for storing power-up output values and configuration registers without requiring external EEPROM.
Offers flexible reference voltage options including device VDD, external VREF pin, or internal band gap source.
Supports programmable gain settings of 1x or 2x when utilizing external reference voltages.
Includes power-down modes that disconnect the output buffer or select specific pull-down resistor values.

Applications

Set point or offset trimming in industrial control systems
Sensor calibration circuits
Low-power portable instrumentation
Data acquisition systems

Procurement Notes

Verify the ordering suffix 'MG' corresponds to the 10-lead MSOP package type as specified in the datasheet. Confirm the '-E' designation indicates the extended temperature range variant (-40°C to +125°C). Ensure the MTP programming requirements, specifically the high-voltage level on the LAT/HVC pin, are supported by the host system design.

Selection Notes

Select this model for applications requiring persistent DAC states after power loss using the onboard MTP memory. Choose the 12-bit resolution version when higher precision is needed compared to the 8-bit or 10-bit variants. Verify that the single-channel configuration meets the system requirements, as dual-channel options exist within the same family.

Part Context

This component belongs to the MCP48CXBXX family of 8-bit, 10-bit, and 12-bit DACs. The 'MCP48CMB' prefix specifically denotes devices with Nonvolatile Memory (MTP), distinguishing them from the volatile 'MCP48CVB' series. The '21' suffix indicates a single-channel, 12-bit resolution device.
