MCP48CMB14T-E/ML

Overview

The MCP48CMB14T-E/ML is a quad-channel, 10-bit 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 maximum Integral Nonlinearity (INL) of ±0.25 LSB, and a typical offset error of ±1.1 mV. The MTP memory allows for 32 user-programmable write cycles per location.

Feature Summary

• Integrated MTP nonvolatile memory retains DAC codes and configuration settings across power cycles.
• Flexible reference input options including VDD, external VREF pin, or internal band gap.
• Configurable output gain settings of 1x or 2x depending on the selected reference source.
• Power-down modes allow for high-impedance output states with selectable pull-down resistors.

Applications

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

Procurement Notes

Verify that the ordering suffix 'T' corresponds to tape-and-reel packaging and '/ML' indicates the 20-lead QFN package. Confirm the '-E' suffix denotes the extended temperature range (-40°C to +125°C). Ensure the specific revision matches the required datasheet version DS20006556B.

Selection Notes

Select this component when quad-channel output is required alongside nonvolatile storage for power-up defaults. The 10-bit resolution offers a balance between precision and speed. Consider the 1.8V operation capability if system power constraints are tight, noting that analog specifications may be reduced at lower voltages.

Part Context

This part belongs to the MCP48CXBX4/8 family, which includes volatile (CVB) and nonvolatile (CMB) variants in 8-bit, 10-bit, and 12-bit resolutions. The 'X' represents the resolution digit (0, 1, or 2), and 'B' specifically designates the MTP memory option. The '4' indicates a quad-channel configuration housed in a 20-lead package.

Replacement Considerations

For volatile memory requirements, consider the MCP48CVB14T-E/ML. For octal channel configurations, review the MCP48CMB18 series. Higher resolution needs may require the MCP4921 or MCP4922 families, though these lack integrated nonvolatile memory.
