MCP47FVB24T-20E/ST

Digital To Analog Converters Overview

The MCP47FVB24T-20E/ST is a quad-channel, 12-bit Digital-to-Analog Converter (DAC) manufactured by Microchip Technology. It features buffered voltage outputs with rail-to-rail capability and volatile RAM memory. The device operates on a supply voltage ranging from 2.7V to 5.5V for full specifications, or 1.8V to 2.7V for reduced specifications. It utilizes an I²C compatible serial interface supporting Standard (100 kHz), Fast (400 kHz), and High-Speed (up to 3.4 MHz) modes. Key electrical parameters include a typical settling time of 7.8 µs, a maximum INL of ±6 LSB, and a maximum DNL of ±1 LSB. The component is housed in a 20-lead TSSOP package and supports an extended operating temperature range from -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Quad-channel configuration providing four independent buffered voltage outputs within a single integrated circuit.
• I²C serial interface compatibility allowing communication via Standard, Fast, and High-Speed data transfer modes.
• WiperLock™ functionality utilizing high-voltage commands to prevent inadvertent changes to stored output values.
• Flexible reference source options including external VREF pin, internal band gap voltage, or device VDD.

Digital To Analog Converters Applications

• Set point or offset trimming in precision circuits
• Sensor calibration systems
• Low-power portable instrumentation
• Data acquisition systems

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and tape-and-reel quantity. Ensure that the selected variant matches the required memory type, as volatile and nonvolatile versions share identical analog structures but differ in data retention capabilities. Cross-reference the datasheet revision to confirm current manufacturing status and any potential product change notifications.

Digital To Analog Converters Selection Notes

Select this component when a quad-channel DAC with I²C connectivity and volatile storage is required. Consider the MCP47FEB24T-20E/ST if nonvolatile EEPROM memory is necessary to retain settings after power loss. Evaluate the power supply constraints, noting that operation below 2.7V results in reduced analog specifications. Confirm that the application environment falls within the specified -40°C to +125°C temperature range for optimal performance.
