MCP47FVB04-20E/ST

Digital To Analog Converters Overview

The MCP47FVB04-20E/ST is a quad-channel, 10-bit buffered voltage output Digital-to-Analog Converter (DAC) from Microchip Technology. It features volatile RAM memory and communicates via an I²C compatible interface supporting Standard (100 kbps), Fast (400 kbps), and High-Speed (up to 3.4 Mbps) modes. The device operates on a supply voltage of 2.7V to 5.5V for full specifications or 1.8V to 2.7V with reduced analog performance. It provides rail-to-rail outputs with a typical settling time of 7.8 µs and includes power-on/brown-out reset protection.

Digital To Analog Converters Feature Summary

• Quad-channel configuration with 10-bit resolution providing 1024 distinct output steps
• I²C serial interface with support for standard, fast, and high-speed data transfer rates
• Rail-to-rail buffered voltage outputs with selectable reference sources including VDD, external VREF, or internal band gap
• Low-power operation with configurable power-down modes and high-voltage WiperLock™ functionality

Digital To Analog Converters Applications

• Set point or offset trimming in precision circuits
• Sensor calibration systems requiring multi-channel adjustment
• Low-power portable instrumentation
• Data acquisition systems
• Motor control applications

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature range. Ensure the selected variant matches the required memory type, as this model utilizes volatile RAM rather than nonvolatile EEPROM. Cross-reference the datasheet revision number to validate electrical characteristics and timing parameters before finalizing procurement.

Digital To Analog Converters Selection Notes

Select this component when a quad-channel DAC with 10-bit resolution is required. Confirm that volatile memory meets system requirements, as values are lost upon power loss. Verify that the I²C bus speed supports the desired communication rate and that the operating voltage aligns with the 2.7V to 5.5V specification for optimal performance.

Digital To Analog Converters Part Context

This part belongs to the MCP47FXBX4/8 family of digital-to-analog converters. The 'F' indicates the series, 'V' denotes volatile memory, 'B' specifies 10-bit resolution, and '04' identifies the quad-channel configuration. The '-20E/ST' suffix designates the 20-lead TSSOP package with extended industrial temperature range capabilities.

Digital To Analog Converters Replacement Considerations

Direct replacements within the same family include MCP47FVB04T-E/ML (same function, different packaging). For nonvolatile alternatives, consider the MCP47FEB04 series. Ensure any substitute maintains the 10-bit resolution and quad-channel architecture while verifying pin compatibility.
