MCP48CMB02-E/MG

Overview

The MCP48CMB02-E/MG is a dual-channel, 8-bit buffered voltage output Digital-to-Analog Converter (DAC) featuring Multi-Time Programmable (MTP) memory and an SPI serial interface. It operates within a supply voltage range of 2.7V to 5.5V, with reduced specifications available for 1.8V to 2.7V operation. The device provides 256 resolution steps per channel and includes 32 MTP locations for nonvolatile storage. Key electrical parameters include a typical settling time of 16 µs, a maximum full-scale error of 2.5 LSB, and a gain error of ±1% of FSR. It supports SPI write speeds up to 50 MHz and read speeds up to 25 MHz.

Feature Summary

• Integrated MTP memory allows user programming of DAC settings and configuration registers for power-up recall.

Applications

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

Procurement Notes

Verify the specific package marking and date code against the manufacturer's latest documentation to ensure authenticity. Confirm that the ordering suffix corresponds to the required tape-and-reel or tube packaging format. Check for any regional compliance certifications such as RoHS status before finalizing procurement orders.

Selection Notes

Select this component when dual-channel 8-bit resolution is sufficient for the application requirements. Ensure the system design accommodates the high-voltage requirement on the LAT/HVC pin for MTP programming operations. Verify that the SPI interface timing constraints align with the host controller capabilities.

Part Context

This part belongs to the MCP48CXBXX family of digital-to-analog converters from Microchip Technology. The 'M' in the model number indicates the use of Multi-Time Programmable memory, distinguishing it from volatile RAM variants. The 'B' denotes the 8-bit resolution level within the product line.

Replacement Considerations

Direct replacements within the same family include MCP48CVB02 for volatile memory applications or MCP48CMB12/22 for higher resolution needs. Cross-family alternatives should be evaluated based on pin compatibility and performance specifications.
