MCP47FVB08T-E/MQ

Digital To Analog Converters Overview

The MCP47FVB08T-E/MQ is an octal-channel, 8-bit volatile Digital-to-Analog Converter (DAC) manufactured by Microchip Technology. It features a buffered voltage output with rail-to-rail capability and communicates via an I2C-compatible serial interface supporting Standard (100 kbps), Fast (400 kbps), and High-Speed (up to 3.4 Mbps) modes. The device operates within a supply voltage range of 2.7V to 5.5V for full specifications, or 1.8V to 2.7V for reduced analog performance. It offers selectable voltage reference sources including VDD, external VREF, or an internal band gap, with gain options of 1x or 2x when using the external reference. The component is housed in a 20-lead 5 x 5 mm VQFN package and supports an extended operating temperature range from -40°C to +125°C.

Digital To Analog Converters Feature Summary

• WiperLock™ functionality prevents inadvertent changes to stored output values using high-voltage commands on dedicated pins.
• Configurable power-down modes allow selection between high-impedance output buffering or specific pull-down resistor values.
• Integrated Power-on Reset and Brown-out Reset protection ensures reliable initialization and state retention during voltage fluctuations.

Digital To Analog Converters Applications

• Set point or offset trimming
• Sensor calibration
• Low-power portable instrumentation
• PC peripherals
• Data acquisition systems

Digital To Analog Converters Procurement Notes

Verify the ordering suffix 'E/MQ' corresponds to the specified industrial temperature grade (-40°C to +125°C) and the 20-lead VQFN package type. Confirm that the 'T' designation indicates tape-and-reel packaging suitable for automated assembly processes. Ensure the selected variant matches the required volatile memory architecture, as nonvolatile EEPROM options exist within the same family.

Digital To Analog Converters Selection Notes

Select this component when multiple independent analog outputs are required in a compact footprint. The octal configuration provides eight distinct channels, reducing board space compared to single-channel alternatives. Consider the internal band gap reference if an external precision voltage source is unavailable, though utilizing an external VREF pin may offer superior accuracy depending on system requirements.

Digital To Analog Converters Part Context

This part belongs to the MCP47FXBX4/8 family of buffered voltage output DACs. The 'FVB' designation identifies it as an 8-bit resolution device with volatile RAM storage. The '08' suffix specifies the octal channel count, distinguishing it from quad-channel variants. This family shares common interface protocols and electrical characteristics across different resolutions and memory types.
