MCP47CMB11-E/MF

Digital To Analog Converters Overview

The MCP47CMB11-E/MF is a single-channel, 10-bit Digital-to-Analog Converter (DAC) manufactured by Microchip Technology. It features buffered voltage output and utilizes an I2C serial interface for communication. The device incorporates Multi-Time Programmable (MTP) nonvolatile memory to retain configuration and data values. It operates within a supply voltage range of 1.8V to 5.5V and supports Standard (100 kbps), Fast (400 kbps), and High-Speed (up to 3.4 Mbps) I2C modes. The component is housed in a 10-lead DFN package measuring 3x3 mm and is rated for extended industrial temperatures from -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Integrates MTP nonvolatile memory allowing up to 32 user-programmable write cycles for persistent storage of DAC settings and general-purpose data.
• Provides flexible reference voltage selection including external VREF pin, internal band gap, or device VDD with selectable gain options.
• Supports multiple I2C operating speeds including High-Speed mode up to 3.4 Mbps for efficient data transfer.
• Includes power-down modes that disconnect the output buffer or select pull-down resistors to minimize current consumption.

Digital To Analog Converters Applications

• Set point or offset trimming in precision instrumentation
• Sensor calibration systems requiring nonvolatile data retention
• Low-power portable instrumentation devices
• PC peripherals and data acquisition systems

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature grade. Confirm the E designation indicates the extended temperature range variant. Ensure the MTP programming requirements are accounted for during system design, specifically the high-voltage level needed on the LAT/HVC pin for memory writes.

Digital To Analog Converters Selection Notes

Select this model when a single-channel buffered output with nonvolatile memory is required. Compare against volatile variants like the MCP47CVB11 if data retention is not necessary. Consider the 10-bit resolution and I2C interface compatibility with the host microcontroller. Verify that the 3x3 DFN package fits the available PCB footprint constraints.

Digital To Analog Converters Part Context

This component belongs to the MCP47CXBXX family of digital-to-analog converters. The family includes 8-bit, 10-bit, and 12-bit resolutions with both single and dual channel configurations. The 'M' in the part number denotes the use of MTP nonvolatile memory, distinguishing it from the 'V' series which uses volatile RAM. The '1' indicates 10-bit resolution, and 'B' signifies the buffered voltage output architecture.

Digital To Analog Converters Replacement Considerations

The MCP47CVB11-E/MF serves as a direct functional substitute if nonvolatile memory retention is not required. For applications needing higher resolution, the MCP47CMB21-E/MF offers 12-bit performance within the same package. Ensure any replacement maintains compatible I2C addressing and voltage levels.
