MCP48CMD11-E/UN

Overview

The MCP48CMD11-E/UN is a single-channel, 10-bit buffered voltage output Digital-to-Analog Converter (DAC) featuring Multi-Time Programmable (MTP) nonvolatile memory. It operates on a single supply voltage ranging from 2.7V to 5.5V, with reduced specifications available between 1.8V and 2.7V. The device utilizes an SPI serial interface supporting write speeds up to 50 MHz and read speeds up to 25 MHz. Key electrical characteristics include a typical settling time of 4 µs, a gain error of ±0.6% of Full Scale Range (FSR), and an Integral Nonlinearity (INL) specification of ±1 LSB. The unit is housed in a 10-lead MSOP package and supports an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Integrates MTP nonvolatile memory for retaining power-up output values and configuration registers without external backup power.
• Offers flexible DAC voltage reference source options including device VDD, external VREF pin, or internal band gap voltage.
• Provides selectable output gain modes of 1x (unity) or 2x when not using the internal VDD as the voltage source.
• Includes Power-on/Brown-out Reset (POR/BOR) protection and configurable power-down modes to minimize current consumption.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature grade. Ensure that the LAT/HVC pin voltage requirements are met if MTP programming is required during system integration. Confirm compliance with RoHS directives and check for any specific environmental compliance declarations relevant to the procurement region.

Selection Notes

Select this component when a single-channel 10-bit resolution is sufficient for the application's dynamic range requirements. Consider the MTP feature if the design requires field-programmable calibration constants or user-defined settings that must persist across power cycles. Evaluate the SPI interface speed requirements against the 50 MHz write limit and ensure the system logic levels are compatible with the specified input thresholds.

Part Context

This part belongs to the MCP48CXDX1/2 family of digital-to-analog converters, which encompasses single and dual channel variants with 8, 10, and 12-bit resolutions. The 'CMD' designation indicates the inclusion of nonvolatile MTP memory, distinguishing it from volatile counterparts like the CVD series. The 'E' suffix typically denotes the extended temperature range variant suitable for industrial environments.

Replacement Considerations

Direct replacements within the same family include other MCP48CMDxx parts with different resolutions or channel counts, provided the pinout and memory features align with the design constraints. Cross-family replacements require careful evaluation of interface compatibility, resolution differences, and package dimensions.
