MCP48CMD12-E/MG

Overview

The MCP48CMD12-E/MG is a dual-channel, 12-bit buffered voltage output Digital-to-Analog Converter (DAC) featuring Multi-Time Programmable (MTP) memory. It operates on a single supply ranging from 2.7V to 5.5V and supports an SPI serial interface with write speeds up to 50 MHz. The device includes an internal band gap reference of 1.214V typical, selectable gain options of 1x or 2x, and power-down modes for low-power applications. It provides 32 MTP write cycles for nonvolatile storage of configuration and data values.

Feature Summary

• Dual-channel architecture with independent DAC outputs
• Nonvolatile MTP memory for persistent configuration storage
• High-speed SPI interface supporting 50 MHz writes
• Internal band gap voltage reference source

Applications

• Set point or offset trimming in industrial systems
• Sensor calibration circuits
• Low-power portable instrumentation
• PC peripherals requiring analog output control

Procurement Notes

Verify the specific package suffix 'MG' against official Microchip documentation to confirm pinout and thermal characteristics. Ensure the ordering code matches the required MTP capacity and temperature range specifications before procurement.

Selection Notes

Select this component when dual-channel 12-bit resolution with nonvolatile memory retention is required. Consider the 1.8V to 2.7V reduced specification range if operating at lower voltages. Verify that the external circuitry can support the high-voltage programming requirements for the MTP memory.

Part Context

This part belongs to the MCP48CXDX1/2 family, which offers single and dual channel configurations with resolutions from 8-bit to 12-bit. The 'CMD' designation indicates the inclusion of nonvolatile MTP memory, distinguishing it from volatile RAM-based variants within the same series.

Replacement Considerations

Direct replacements include other parts within the MCP48CXDX1/2 family such as MCP48CVD12-E/MG for volatile memory versions, or MCP48CMD22-E/MG for 12-bit single-channel equivalents if channel count allows modification.
