MCP47CMB04T-20E/ST

Digital To Analog Converters Overview

The MCP47CMB04T-20E/ST is a dual-channel, 8-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 1.8V to 5.5V, supporting full specifications from 2.7V to 5.5V and reduced specifications from 1.8V to 2.7V. The device includes 32 MTP locations for general-purpose data storage and offers selectable voltage reference sources including VDD, external VREF, or an internal band gap. It supports Standard (100 kbps), Fast (400 kbps), and High-Speed (up to 3.4 Mbps) I2C modes.

Digital To Analog Converters Feature Summary

• Dual-channel buffered voltage outputs with integrated MTP nonvolatile memory
• Configurable I2C interface supporting Standard, Fast, and High-Speed modes
• Flexible voltage reference selection with gain options of 1x or 2x
• Power-on/Brown-out reset protection and low-power shutdown modes

Digital To Analog Converters Applications

• Set point or offset trimming in precision circuits
• Sensor calibration systems
• Low-power portable instrumentation
• PC peripherals requiring analog signal generation
• Data acquisition systems

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape-and-reel configuration. Ensure that the required operating voltage and temperature ranges align with the system design constraints before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when dual-channel analog output is required alongside persistent configuration storage without external EEPROMs. Consider the 1.8V to 5.5V operating range and the availability of High-Speed I2C modes for faster communication requirements compared to standard interfaces.

Digital To Analog Converters Part Context

This device belongs to the MCP47CXBXX family of single and dual channel DACs. It shares architectural similarities with volatile memory variants like the MCP47CVBXX but distinguishes itself through the inclusion of user-programmable MTP memory. The family provides 8-bit, 10-bit, and 12-bit resolution options across various package types.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include other MCP47CMBxx variants with different resolutions or channel counts, such as MCP47CMB12 or MCP47CMB01, provided pin compatibility and memory requirements are met.
