MCP47CMB01-E/MG

Digital To Analog Converters Overview

The MCP47CMB01-E/MG is a single-channel, 8-bit buffered voltage output Digital-to-Analog Converter (DAC) from Microchip Technology. It features Multi-Time Programmable (MTP) nonvolatile memory for power-up output values and configuration registers. The device operates on a supply voltage of 2.7V to 5.5V with full specifications, or 1.8V to 2.7V with reduced analog performance. It utilizes an I2C serial interface supporting Standard (100 kHz), Fast (400 kHz), and High-Speed (up to 3.4 MHz) modes. Key electrical parameters include a typical settling time of 16 µs, a gain error of ±1% of Full Scale Range (FSR), and an Integral Nonlinearity (INL) of ±0.1 LSB. The component is housed in a 10-lead MSOP package and supports an extended operating temperature range from -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Integrated MTP nonvolatile memory allows user programming up to 32 times per register for persistent data storage.
• Configurable voltage reference options including VDD, external VREF pin, or internal band gap source.
• Supports multiple I2C clock speeds including High-Speed mode for rapid communication.
• Includes Power-on/Brown-out Reset protection and configurable power-down modes.

Digital To Analog Converters Applications

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix '-MG' corresponds to the 10-lead MSOP package type as documented in the datasheet. Confirm that the 'E' suffix indicates compliance with environmental standards. Ensure the selected variant matches the required memory type (MTP) and resolution (8-bit). Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when a single-channel DAC with nonvolatile memory retention is required. The 8-bit resolution provides 256 steps suitable for moderate precision applications. Consider the I2C interface compatibility with the host controller's available pins and supported clock speeds. Evaluate the power supply constraints, noting that operation below 2.7V results in reduced analog specifications. Verify that the MSOP package fits within the available PCB footprint and thermal requirements.

Digital To Analog Converters Part Context

This device belongs to the MCP47CXBXX family of 8/10/12-bit DACs. The 'M' in the model number designates the inclusion of Multi-Time Programmable (MTP) nonvolatile memory, distinguishing it from volatile RAM variants. The 'B' indicates the 8-bit resolution class. This family shares common architectural features such as the WiperLock™ technology and similar I2C control logic across different channel counts and resolutions.

Digital To Analog Converters Replacement Considerations

Direct replacements within the same family include other MCP47CMBxx variants with different resolutions or channel counts, provided the interface and package are compatible. Volatile memory versions like MCP47CVB01 may serve as substitutes if nonvolatile retention is not critical. External components must be evaluated for any changes in reference voltage handling or power consumption characteristics.

Digital To Analog Converters FAQ

How many times can the MTP memory be programmed?

The MTP memory can be written by the user up to 32 times for each specific register location. After 32 writes, subsequent write commands are inhibited.

What is the function of the LAT/HVC pin?

The LAT/HVC pin serves dual purposes. It acts as a latch input for updating outputs and requires a high-voltage level (typically 7.5V) to successfully program the MTP memory locations.

Can the device operate at 1.8V?

Yes, the device can operate at 1.8V to 2.7V, but this range offers reduced device specifications compared to the full 2.7V to 5.5V operating range.
