MCP48CMB01-E/MG

Overview

The MCP48CMB01-E/MG is a single-channel, 8-bit Digital-to-Analog Converter (DAC) featuring Multi-Time Programmable (MTP) nonvolatile memory and an SPI serial interface. It operates on a single supply voltage ranging from 2.7V to 5.5V, with reduced specifications available between 1.8V and 2.7V. The device provides a buffered voltage output with selectable unity or 2x gain. Key electrical parameters include a typical settling time of 16 µs, a maximum SPI write speed of 50 MHz, and an operating temperature range of -40°C to +125°C. It incorporates Power-on Reset (POR) and Brown-out Reset (BOR) protection.

Feature Summary

• Integrated MTP memory allows user-programmable storage for power-up values and configuration registers.
• Flexible reference input options including internal band gap, VDD, or external VREF pin.
• High-speed SPI interface supporting up to 50 MHz write operations.
• Configurable power-down modes for low-power applications.

Applications

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

Procurement Notes

Verify the specific package marking against the datasheet to confirm the MG suffix corresponds to the MSOP-10 package type. Ensure the E suffix indicates the extended industrial temperature rating (-40°C to +125°C). Confirm that the MTP memory has not been previously programmed if a blank state is required for your application.

Selection Notes

Select this component when volatile memory is insufficient for retaining DAC settings after power loss. The 8-bit resolution is suitable for general-purpose analog control where high precision is not critical. Consider the 2x gain option if the external reference voltage is limited to half the supply voltage. Verify that the system can provide the necessary high-voltage level on the LAT/HVC pin for MTP programming.

Part Context

This part belongs to the MCP48CXBXX family of 8/10/12-bit DACs. The 'M' in the model number designates the inclusion of Nonvolatile Memory (MTP), distinguishing it from the 'CVB' series which uses volatile RAM. The '01' suffix indicates a single-channel output configuration, while 'MG' specifies the MSOP-10 package.

Replacement Considerations

For direct replacements with MTP memory, consider the MCP48CMB11 (10-bit) or MCP48CMB21 (12-bit) for higher resolution. If volatile memory is acceptable, the MCP48CVB01 offers similar functionality without nonvolatile storage. Dual-channel equivalents are available as MCP48CMB02.
