MCP47FVB02A0T-E/ST

Digital To Analog Converters Overview

The MCP47FVB02A0T-E/ST is a dual-channel, 8-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. It provides rail-to-rail output with a typical settling time of 6 µs. Power consumption is less than 180 µA in normal operation and approximately 650 nA in power-down mode. The component is housed in an 8-lead TSSOP package and supports an extended operating temperature range from -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Dual-channel architecture with 8-bit resolution providing 256 distinct output steps per channel.
• Configurable voltage reference sources including external VREF pin, internal band gap, or device VDD.
• Integrated output buffer with selectable gain settings of 1x or 2x when using the external VREF pin.
• Built-in power-on and brown-out reset protection mechanisms to ensure reliable initialization.

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the device variant corresponds to the volatile memory specification rather than non-volatile EEPROM options. Ensure compatibility with the target system's I2C bus speed and voltage levels before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution is required without the need for data retention during power loss. Consider the 8-bit resolution limits for applications requiring higher precision. Evaluate the power-down current requirements against system standby constraints. Verify that the 6 µs settling time meets the timing requirements of the specific application cycle.

Digital To Analog Converters Part Context

This part belongs to the MCP47FVBXX family of single and dual-channel DACs. It shares functional similarities with the MCP47FEBXX series, which utilizes non-volatile EEPROM instead of volatile RAM. Both families support high-voltage command capabilities and similar I2C interfaces, allowing for potential design flexibility between volatile and non-volatile storage requirements.
