MCP48CMB24T-20E/ST

Overview

The MCP48CMB24T-20E/ST is a quad-channel, 12-bit buffered voltage output Digital-to-Analog Converter (DAC) featuring Multi-Time Programmable (MTP) nonvolatile memory. It operates on a supply voltage range of 2.7V to 5.5V and utilizes a 4-wire SPI serial interface with write speeds up to 50 MHz. The device provides an internal band gap reference (1.214V typical), supports external VREF inputs, and offers gain options of 1x or 2x. It includes power-on/brown-out reset protection, configurable power-down modes, and general-purpose MTP locations for user data storage.

Feature Summary

• Integrates nonvolatile MTP memory for retaining DAC output values and configuration settings across power cycles.
• Provides buffered voltage outputs with selectable gain factors of 1x or 2x depending on the reference source selection.
• Supports flexible reference voltage sourcing from device VDD, an external pin, or an internal band gap circuit.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature grade. Ensure the design accounts for the high-voltage programming requirements on the LAT/HVC pin if MTP functionality is utilized. Confirm that the selected quantity matches the available packaging format specified by the supplier.

Selection Notes

Select this component when quad-channel 12-bit resolution with nonvolatile memory retention is required. Compare against volatile variants like the MCP48CVB24 if power loss persistence is unnecessary. Verify that the system can provide the necessary high-voltage level on the LAT/HVC pin for MTP programming operations.

Part Context

This part belongs to the MCP48CXBX4/8 family of digital-to-analog converters. It shares the same core architecture and interface as other members but is distinguished by its 12-bit resolution and nonvolatile MTP memory configuration. The 'T' suffix indicates tape and reel packaging, while '/ST' denotes the 20-lead TSSOP package.

Replacement Considerations

Publicly confirmed substitutes include the MCP48CMB24T-20E/P (SOIC package) and the MCP48CMB24-20E/ST (tube packaging). These parts maintain identical electrical specifications and pinouts, differing only in the physical package style and shipping container format.
