MCP48CMD11T-E/UN

Overview

The MCP48CMD11T-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, with reduced specifications available between 1.8V and 2.7V. The device utilizes a 3-wire SPI interface supporting write speeds up to 50 MHz and read speeds up to 25 MHz. Key electrical parameters include a typical settling time of 4 µs, an integral nonlinearity (INL) of ±1 LSB, and a differential nonlinearity (DNL) of ±1 LSB. It offers reference source options including VDD, external VREF, or an internal 1.214V bandgap, with gain settings of 1x or 2x.

Feature Summary

• Integrates MTP nonvolatile memory for retaining power-up output values and configuration data without battery backup.
• Provides flexible DAC voltage reference selection among device VDD, external VREF pin, or internal band gap.
• Supports configurable output gain of 1x or 2x when using external reference sources.
• Includes power-down modes that disconnect the output buffer or select specific pull-down resistor values.

Applications

• Set point or offset trimming in industrial control systems
• Sensor calibration circuits requiring precise analog adjustments
• Low-power portable instrumentation devices
• Data acquisition systems needing buffered analog outputs

Procurement Notes

Verify the ordering suffix 'T-E/UN' corresponds to the UN package type and temperature grade specified in the official datasheet. Confirm that the MTP programming requirements, specifically the high-voltage level on the LAT/HVC pin, are supported by the host system design before finalizing procurement.

Selection Notes

Select this component when a single-channel 10-bit resolution with nonvolatile storage is required. Ensure the application supports the SPI interface timing constraints and the LAT/HVC pin voltage requirements for MTP programming. Compare against volatile variants if persistent storage is not necessary for the specific use case.

Part Context

This part belongs to the MCP48CXDX1 family of digital-to-analog converters. It shares architectural similarities with other members like the MCP48CMD12 but differs in channel count and resolution. The family is characterized by its WiperLock technology and flexible reference input options, designed for precision applications in extended temperature ranges.

Replacement Considerations

Direct substitutes within the same family include MCP48CMD11T-E/MF or MCP48CMD11T-E/ML depending on package preference. For dual-channel requirements, consider the MCP48CMD12 series. Verify pin compatibility and MTP programming voltage support when substituting.
