MCP47FVB04T-20E/ST

Digital To Analog Converters Overview

The MCP47FVB04T-20E/ST is a quad-channel, 8-bit voltage output Digital-to-Analog Converter (DAC) manufactured by Microchip Technology. It features 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, with reduced specifications available from 1.8V to 2.7V. It utilizes volatile RAM memory for DAC register storage and includes Power-on/Brown-out Reset protection. The component is housed in a 20-lead TSSOP package and supports an extended operating temperature range of -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Quad-channel buffered voltage output architecture with rail-to-rail capability
• I²C serial interface with multiple speed modes and user-programmable slave addresses
• Configurable voltage reference sources including VDD, external VREF pin, and internal band gap
• Power-down modes allowing high-impedance output or selectable pull-down resistors

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 specific ordering suffix against the manufacturer's current documentation to confirm package type and tape-and-reel configuration. Ensure the selected variant matches the required memory type, as this family includes both volatile and nonvolatile options. Cross-reference the datasheet revision date to confirm compatibility with your design requirements.

Digital To Analog Converters Selection Notes

Select this component when a quad-channel solution with 8-bit resolution is required. Consider the MCP47FXB1X or MCP47FXB2X variants if higher resolution is needed. Verify that the system power supply remains above 2.7V for full specification compliance. Check if nonvolatile EEPROM storage is necessary, in which case the MCP47FEBxx series should be evaluated instead.

Digital To Analog Converters Part Context

This part belongs to the MCP47FXBX4/8 family of digital-to-analog converters. The family differentiates between volatile (RAM) and nonvolatile (EEPROM) memory versions, indicated by the 'V' and 'E' characters respectively. The '04' designation specifies the 8-bit resolution and quad-channel configuration within this product line.

Digital To Analog Converters Replacement Considerations

Direct replacements within the same family include MCP47FVB04T-E/MQ (VQFN package). For higher resolution needs, consider MCP47FVB14T-20E/ST (10-bit) or MCP47FVB24T-20E/ST (12-bit). Nonvolatile alternatives are available in the MCP47FEB04 series.
