MCP47CMB02-E/UN

Digital To Analog Converters Overview

The MCP47CMB02-E/UN is a dual-channel, 8-bit buffered voltage output Digital-to-Analog Converter (DAC) featuring Multi-Time Programmable (MTP) nonvolatile memory and an I2C serial interface. It operates within a supply voltage range of 1.8V to 5.5V and supports Standard (100 kHz), Fast (400 kHz), and High-Speed (up to 3.4 MHz) communication modes. The device provides 1 LSB Integral Nonlinearity (INL) specification, configurable power-down modes, and Power-on/Brown-out Reset protection. It is housed in a 10-lead MSOP package and functions across an extended temperature range of -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Dual-channel architecture with integrated MTP nonvolatile memory for persistent storage of DAC values and configuration registers.
• Configurable reference voltage sources including VDD, external VREF pin, or internal band gap, with selectable gain options.
• I2C compatible serial interface supporting multiple clock speeds and register-defined slave address selection via physical pins.

Digital To Analog Converters Applications

• Set point or offset trimming
• Sensor calibration
• Low-power portable instrumentation

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature grade. Ensure compatibility with system voltage levels and I2C bus requirements before integration. Cross-reference the datasheet revision to confirm all electrical characteristics match design specifications.

Digital To Analog Converters Selection Notes

Select this component when dual-channel analog output with nonvolatile retention is required. Verify that the 8-bit resolution meets application accuracy needs. Confirm that the I2C address configuration using A0/A1 pins fits the system topology. Check if the MSOP-10 package dimensions align with the PCB layout constraints.

Digital To Analog Converters Part Context

This part belongs to the MCP47CXBXX family of 8-bit, 10-bit, and 12-bit DACs from Microchip Technology. The 'M' in the model number indicates the inclusion of MTP nonvolatile memory, distinguishing it from volatile RAM variants. The 'B' denotes the dual-channel configuration, while '02' specifies the 8-bit resolution.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include MCP47CVB02-E/UN for volatile memory applications or MCP47CMD02-E/UN for SPI interface requirements. Ensure functional equivalence regarding channel count, resolution, and package footprint when considering alternatives.
