MCP48CMD11-E/MG

Overview

The MCP48CMD11-E/MG is a single-channel, 10-bit Digital-to-Analog Converter (DAC) featuring Multi-Time Programmable (MTP) nonvolatile memory and an SPI serial interface. It operates on a single supply voltage ranging from 2.7V to 5.5V, with reduced specifications available for the 1.8V to 2.7V range. The device provides buffered voltage outputs with selectable unity or 2x gain options. Key electrical characteristics include a typical settling time of 4 µs, a maximum Integral Nonlinearity (INL) of ±0.25 LSB, and a typical Gain Error of ±0.1% of Full Scale Range (FSR). It supports SPI clock speeds up to 50 MHz for write operations and includes Power-on Reset (POR) and Brown-out Reset (BOR) protection.

Feature Summary

• Integrated MTP memory allows user programming of DAC codes and configuration registers without external EEPROM.
• Flexible reference input options including VDD, external VREF pin, and internal band gap voltage.
• SPI-compatible serial interface supporting high-speed write and read operations.
• Configurable power-down modes to minimize current consumption in low-power applications.

Applications

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

Procurement Notes

Verify the specific ordering suffix '-MG' against the manufacturer's official package drawings to confirm the 10-lead MSOP physical dimensions and pinout compatibility. Ensure the 'E' designation matches the required extended temperature range specifications (-40°C to +125°C) for your application environment. Cross-reference the datasheet revision date to confirm the latest electrical characteristics and timing parameters are applied.

Selection Notes

Select this component when a single-channel 10-bit resolution is sufficient for the application's accuracy requirements. Choose this part over volatile variants if nonvolatile storage of the DAC output value at power-up is required. Consider the 2x gain option only if an external reference voltage limited to VDD/2 is utilized. Verify that the system's digital logic levels are compatible with the SPI interface thresholds across the operating voltage range.

Part Context

This device belongs to the MCP48CXDX1/2 family of 8/10/12-bit DACs from Microchip Technology. The 'C' indicates the inclusion of MTP memory, distinguishing it from the 'V' series which uses volatile RAM. The 'D' denotes the 10-bit resolution variant, while 'X' represents the package type code corresponding to the MSOP-10 package in this specific ordering suffix.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. Users should consult the manufacturer's official cross-reference documentation or contact technical support directly for verified equivalent components.
