MCP47CMB02-E/MF

Digital To Analog Converters Overview

The MCP47CMD02-E/UN is a dual-channel, 8-bit buffered voltage output Digital-to-Analog Converter (DAC) from the MCP47CXBXX family. It features an I2C serial interface and utilizes Multi-Time Programmable (MTP) nonvolatile memory for data retention. The device operates within a supply voltage range of 1.8V to 5.5V, supporting Standard (100 kHz), Fast (400 kHz), and High-Speed (up to 3.4 MHz) modes. It includes an internal band gap reference, configurable gain options, and power-down modes. The component is housed in a 10-lead MSOP package and supports an extended operating temperature range from -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Integrates MTP nonvolatile memory allowing up to 32 user-programmable writes per register for persistent storage of DAC output values and configuration settings.
• Supports flexible voltage reference selection including VDD, external VREF pin, or internal band gap, with selectable unity or 2x gain configurations.
• Features WiperLock technology for simultaneous updating of both DAC channels via a single latch command.

Digital To Analog Converters Applications

• Set point or offset trimming in industrial control systems
• Sensor calibration circuits requiring nonvolatile output retention
• Low-power portable instrumentation
• PC peripherals and data acquisition systems

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with system voltage levels and I2C bus speeds. Confirm availability through authorized distributors as supply status may vary. Cross-reference the datasheet revision to ensure all electrical characteristics match design requirements.

Digital To Analog Converters Selection Notes

Select this component when dual-channel 8-bit resolution with nonvolatile memory is required. Compare against volatile variants if power loss data retention is not needed. Verify that the MSOP-10 package fits the PCB layout constraints. Ensure the application voltage does not exceed the maximum ratings specified in the datasheet.

Digital To Analog Converters Part Context

This part belongs to the MCP47CXBXX family of 8-bit, 10-bit, and 12-bit DACs. It shares architectural similarities with other members like the MCP47CVB02 but differs in memory type. The 'E' suffix indicates an extended temperature range, while '/UN' specifies the MSOP-10 package. It complements single-channel versions by providing two independent outputs on one die.

Digital To Analog Converters Replacement Considerations

Direct substitutes include other MCP47CMB02 variants with different packages such as DFN-10 or QFN-16. Volatile equivalents like MCP47CVB02 can be used if nonvolatile memory is unnecessary. Single-channel alternatives like MCP47CMD01 require separate components for dual-output applications.
