MCP48CMB02-E/MF

Overview

The MCP48CMB02-E/MF 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 for full specifications, or 1.8V to 2.7V with reduced analog performance. The device supports reference sources including VDD, external VREF, and an internal bandgap. Key electrical parameters include a settling time of 16 µs, gain error of ±1% FSR, and integral nonlinearity of ±1 LSB. It offers power-down modes and latch-up protection exceeding ±100 mA.

Feature Summary

• Integrated MTP memory allows user-programmable storage of DAC settings and configuration bits for power-on recall.
• Dual-channel architecture provides independent buffered voltage outputs with selectable unity or 2x gain.
• SPI interface supports high-speed write operations up to 50 MHz and read operations up to 25 MHz.
• Flexible reference options include device VDD, external VREF pin, and internal bandgap voltage.

Applications

• Set point or offset trimming in industrial control systems
• Sensor calibration requiring precise voltage references
• Low-power portable instrumentation
• Data acquisition systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure the LAT/HVC programming voltage requirements are met if utilizing the nonvolatile memory features. Confirm availability through authorized distributors as stock levels fluctuate.

Selection Notes

Select this component when dual-channel 8-bit resolution with nonvolatile memory retention is required. Consider the 16-lead QFN package for space-constrained designs. Evaluate the 1.8V to 2.7V operating range if lower power consumption is prioritized over full specification accuracy.

Part Context

This part belongs to the MCP48CXBXX family of digital-to-analog converters. It shares architectural similarities with single-channel variants like the MCP48CMB01 and higher-resolution models such as the MCP48CMB12. The 'MF' suffix typically denotes a specific package variant within the Microchip portfolio.

Replacement Considerations

Direct substitutes within the same family include MCP48CMB01-E/MF for single-channel applications or MCP48CMB12-E/MF for higher resolution needs. Verify pin compatibility and memory specifications before substitution.
