MCP48CMD12-E/MF

Overview

The MCP48CMD12-E/MF is a dual-channel, 12-bit buffered voltage output Digital-to-Analog Converter (DAC) featuring Multi-Time Programmable (MTP) nonvolatile memory. It operates on a single supply voltage ranging from 2.7V to 5.5V and supports an SPI serial interface with write speeds up to 50 MHz. The device offers selectable reference sources including VDD, external VREF, or an internal band gap. Key electrical specifications include a typical settling time of 4 µs, integral nonlinearity (INL) of ±1 LSB, and gain error of ±0.6% FSR. It is housed in a 10-lead MSOP package and functions within an extended temperature range of -40°C to +125°C.

Feature Summary

• Integrates MTP nonvolatile memory for retaining DAC output values, configuration registers, and general-purpose data across power cycles.
• Provides flexible voltage reference options allowing selection between device supply, external pin, or internal band gap generator.
• Supports high-speed SPI communication with simultaneous latching capability via the LAT pin for synchronized multi-channel updates.

Applications

• Set point or offset trimming in industrial control systems
• Sensor calibration circuits requiring persistent configuration storage
• Low-power portable instrumentation devices

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure the design accommodates the high-voltage requirement on the HVC pin for MTP programming operations. Confirm that the system logic levels are compatible with the specified SPI interface thresholds before integration.

Selection Notes

Select this component when both 12-bit resolution and nonvolatile data retention are required in a compact surface-mount package. Consider the internal band gap option if an external precision reference is not available. Evaluate the power-down modes to ensure they meet the standby current requirements of the target application.

Part Context

This part belongs to the MCP48CXDX family of digital-to-analog converters. It shares architectural similarities with volatile variants like the MCP48CVD12 but distinguishes itself through integrated MTP memory. The 'CMD' designation indicates the dual-channel configuration with nonvolatile capabilities, while 'MF' specifies the 10-lead MSOP packaging format.

Replacement Considerations

The MCP48CVD12-E/MF serves as a direct functional substitute if nonvolatile memory retention is not required. For applications needing higher resolution, the MCP48CMD22-E/MF provides 12-bit performance with additional features. Verify pin compatibility and software register mapping when transitioning between these family members.
