MCP47CMB14T-E/ML

Digital To Analog Converters Overview

The MCP47CMB14T-E/ML is a quad-channel, 10-bit buffered voltage output Digital-to-Analog Converter (DAC) featuring Multi-Time Programmable (MTP) nonvolatile memory and an I2C 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 includes 32 MTP locations per register, requiring a high-voltage level on the LAT/HVC pin for programming. It supports Standard (100 kbps), Fast (400 kbps), and High-Speed (up to 3.4 Mbps) I2C modes. The component is housed in a QFN-20 package and functions across an extended temperature range of -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Quad-channel architecture providing four independent buffered voltage outputs.
• Nonvolatile MTP memory allows user-programmable storage of up to 32 writes per register.
• Flexible reference selection including internal band gap, VDD, or external VREF pin.
• Configurable power-down modes allowing output buffer disconnection or pull-down resistor selection.

Digital To Analog Converters Applications

• Set point or offset trimming
• Sensor calibration
• Low-power portable instrumentation
• PC peripherals
• Data acquisition systems

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with system voltage levels and I2C bus speeds. Confirm that the required MTP programming voltage capability is supported by the host controller circuitry before finalizing procurement.

Digital To Analog Converters Selection Notes

Select this component when multiple isolated DAC channels are required in a compact footprint. The MTP memory option is suitable for applications needing persistent calibration data without external EEPROMs. Verify that the 10-bit resolution meets system accuracy requirements and that the QFN-20 package aligns with PCB layout constraints.

Digital To Analog Converters Part Context

This part belongs to the MCP47CXBXX family of single, dual, and quad channel DACs. It shares core architectural features with other variants in the series, differing primarily in channel count, resolution, and memory type. The 'MB' designation specifically indicates the inclusion of nonvolatile MTP memory rather than volatile RAM found in CVB variants.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include MCP47CMB04-E/ML (8-bit) and MCP47CMB24-E/ML (12-bit). For volatile memory requirements, consider the MCP47CVB14-E/ML. Cross-family replacements require verification of pinout compatibility and electrical specifications.
