MCP48CMB11-E/UN

Digital To Analog Converters Overview

The MCP48CMB11-E/UN is a single-channel, 10-bit Digital-to-Analog Converter (DAC) featuring buffered voltage output and Multi-Time Programmable (MTP) nonvolatile memory. It operates on a supply voltage ranging from 2.7V to 5.5V for full specifications, or 1.8V to 2.7V with reduced analog performance. The device utilizes a four-wire SPI serial interface supporting write speeds up to 50 MHz and read speeds up to 25 MHz. Key electrical parameters include a typical settling time of 16 µs, an integral nonlinearity (INL) specification of ±1 LSB, and a gain error of ±1% of Full Scale Range (FSR).

Digital To Analog Converters Feature Summary

• Integrates MTP nonvolatile memory allowing user-programmable storage of DAC values and configuration registers.
• Provides flexible reference voltage selection between the internal band gap, VDD, or an external VREF pin.
• Supports configurable output gain options of 1x or 2x when utilizing an external reference source.
• Includes power-down modes that disconnect the output buffer or select specific pull-down resistor values.

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the exact ordering suffix against the manufacturer's current datasheet to confirm package type and temperature range compatibility. Ensure the design supports the high-voltage programming requirements necessary for writing to the MTP memory locations. Confirm that the system logic levels are compatible with the specified SPI interface thresholds.

Digital To Analog Converters Selection Notes

Select this component when a single-channel buffered DAC with persistent nonvolatile memory is required. The 10-bit resolution offers a balance between precision and speed. Consider the MTP endurance limit of 32 write cycles per location during the design phase. Verify that the application can accommodate the external high-voltage requirement for memory programming operations.

Digital To Analog Converters Part Context

This part belongs to the MCP48CXBXX family of 8, 10, and 12-bit DACs. It is distinguished by its 'M' designation indicating MTP memory, unlike the 'CV' variant which uses volatile RAM. The 'B' indicates a single channel, while 'UN' specifies the MSOP-10 package. It shares the same core architecture as other members but differs in memory type and channel count.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include MCP48CMB01-E/UN (8-bit) and MCP48CMB21-E/UN (12-bit), provided the resolution difference is acceptable. For volatile memory applications, the MCP48CVB11-E/UN is functionally similar but lacks nonvolatile storage. Cross-family replacements require verification of pinout and interface compatibility.
