MCP48CMD11T-E/MF

Overview

The MCP48CMD11T-E/MF is a single-channel, 10-bit Digital-to-Analog Converter (DAC) featuring Multi-Time Programmable (MTP) nonvolatile memory and an SPI serial interface. It provides buffered voltage outputs with a resolution of 1024 steps. The device operates within a supply voltage range of 2.7V to 5.5V for full specifications, or 1.8V to 2.7V for reduced analog performance. Key electrical parameters 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 internal band gap reference is typically 1.214V. It supports power-down modes and includes Power-on/Brown-out Reset protection.

Feature Summary

• Integrates user-programmable MTP nonvolatile memory for storing DAC output values, configuration registers, and general-purpose data.
• Offers flexible voltage reference selection options including device VDD, external VREF pin, or an internal band gap source.
• Supports configurable output gain settings of 1x or 2x when utilizing an external voltage reference.
• Features a high-speed SPI interface capable of write speeds up to 50 MHz and read speeds up to 25 MHz.

Applications

• Set point or offset trimming in industrial control systems
• Sensor calibration and signal conditioning
• Low-power portable instrumentation
• 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 operation. Confirm compatibility with the host microcontroller's SPI mode and voltage levels before integration.

Selection Notes

Select this component when nonvolatile storage of DAC states is required without external EEPROM. Choose the 10-bit resolution variant for applications needing 1024 output steps. Consider the extended temperature range (-40°C to +125°C) for harsh environments. Verify that the 1 LSB INL specification meets the system accuracy requirements compared to higher-precision alternatives.

Part Context

This part belongs to the MCP48CXDX1/2 family of digital-to-analog converters from Microchip Technology. The family encompasses single and dual channel devices with 8, 10, and 12-bit resolutions. Variants exist with either volatile RAM or nonvolatile MTP memory. The MCP48CMD11T-E/MF specifically denotes the single-channel, 10-bit, nonvolatile version in an MSOP-10 package.

Replacement Considerations

Direct replacements within the same family include other MCP48CMDxx variants with different resolutions or channel counts, provided the pinout and memory requirements align. Volatile counterparts like the MCP48CVD11 may be used if nonvolatile retention is not needed.
