MCP47FVB22A0T-E/ST

Digital To Analog Converters Overview

The MCP47FVB22A0T-E/ST is a dual-channel, 12-bit buffered voltage output Digital-to-Analog Converter (DAC) manufactured by Microchip Technology. It features volatile memory and an I²C 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. Key electrical parameters include a typical settling time of 6 µs, rail-to-rail output capability, and low power consumption of less than 380 µA in normal operation. It utilizes an 8-lead TSSOP package and supports an extended temperature range from -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Dual-channel architecture providing independent 12-bit analog outputs via a shared I²C interface.
• Configurable voltage reference sources including external VREF pin, internal band gap, or device VDD.
• Integrated power-on and brown-out reset protection to ensure reliable startup states.
• Flexible power-down modes allowing output buffer disconnection or selection of pull-down resistors.

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 current documentation to confirm package type and temperature grade. Ensure the component matches the required I²C address configuration and memory volatility characteristics for the target design. Cross-reference the datasheet revision to validate all electrical parameters before finalizing procurement.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution with 12-bit resolution and volatile storage is required. Consider the MCP47FEB22 series if non-volatile EEPROM storage is necessary instead of RAM. Verify that the system's I²C bus speed does not exceed the supported High-Speed mode limits and that the supply voltage remains within the specified operating range for optimal performance.

Digital To Analog Converters Part Context

This part belongs to the MCP47FVBXX family of single and dual-channel DACs. It shares architectural similarities with the MCP47FEBXX series, differing primarily in memory type (volatile RAM versus non-volatile EEPROM). Both families utilize the same I²C interface and support high-voltage commands on the LAT/HVC pin for driving external loads.

Digital To Analog Converters Replacement Considerations

MCP47FEB22A0T-E/ST: Identical electrical specifications but utilizes non-volatile EEPROM instead of volatile RAM for data retention.
