MCP47CMB08-E/ML

Digital To Analog Converters Overview

The MCP47CMB08-E/ML is an octal-channel, 8-bit buffered voltage output Digital-to-Analog Converter (DAC) manufactured by Microchip Technology. It features a Multi-Time Programmable (MTP) nonvolatile memory architecture and communicates via an I2C serial interface. The device operates within a supply voltage range of 2.7V to 5.5V for full specifications, or 1.8V to 2.7V with reduced analog performance. It utilizes a QFN-20 package and supports Standard (100 kbps), Fast (400 kbps), and High-Speed (up to 3.4 Mbps) communication modes.

Digital To Analog Converters Feature Summary

• Octal-channel configuration providing eight independent buffered voltage outputs in a single integrated circuit.
• Nonvolatile MTP memory retains power-up output values and configuration data without external backup power.
• Flexible reference input options allowing selection between the internal band gap, device VDD, or an external VREF pin.
• Integrated WiperLock technology ensures stable DAC settings during programming operations.

Digital To Analog Converters Applications

• Set point or offset trimming in industrial control systems
• Sensor calibration requiring persistent configuration storage
• Low-power portable instrumentation devices
• PC peripherals requiring multi-channel signal generation

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure the design accommodates the high-voltage requirement on the LAT/HVC pin if MTP programming is utilized. Confirm that the I2C address pins are configured correctly for the target system topology.

Digital To Analog Converters Selection Notes

Select this component when multiple isolated DAC channels are required within a compact footprint. The MTP memory variant is suitable for applications needing factory-programmed or field-adjustable output levels that persist across power cycles. Compare channel count and resolution requirements against other family members like the MCP47CVB series if volatile memory suffices.

Digital To Analog Converters Part Context

This part belongs to the MCP47CXBXX family of 8/10/12-bit DACs from Microchip Technology. The 'M' designation indicates the inclusion of Nonvolatile MTP memory, distinguishing it from the 'V' series which uses volatile RAM. The '08' suffix specifies the 8-bit resolution and octal channel configuration.

Digital To Analog Converters Replacement Considerations

Direct functional substitutes within the same family include the MCP47CMB18 and MCP47CMB28 for higher resolutions. For volatile memory applications, the MCP47CVB08 offers identical electrical characteristics without nonvolatile storage capabilities.
