MCP47FVB02A2-E/ST

Digital To Analog Converters Overview

The MCP47FVB02A2-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 kHz), Fast (400 kHz), and High-Speed (up to 3.4 MHz) modes. The device operates within a supply voltage range of 2.7V to 5.5V for full specifications, or 1.8V to 2.7V with reduced analog performance. Key electrical parameters include a typical settling time of 6 µs, rail-to-rail output capability, and power-down current as low as 650 nA. It utilizes 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 discrete output steps per channel.
• I²C-compatible serial interface enabling communication via Standard, Fast, and High-Speed modes.
• Configurable voltage reference sources including external VREF pin, internal band gap, or device VDD.
• Integrated power-on and brown-out reset protection mechanisms.

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 official documentation to confirm package type and temperature grade. Ensure compatibility with system voltage levels and I²C bus speeds. Confirm that the volatile memory requirement aligns with application needs, as data is lost upon power removal. Cross-reference the manufacturer's datasheet for any recent product change notifications or lifecycle status updates before finalizing procurement.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel DAC with I²C connectivity is required. Consider the 8-bit resolution limit for applications not demanding higher precision. Evaluate the power consumption requirements, noting the difference between active and power-down states. Verify that the 8-lead TSSOP package fits the available PCB space. Ensure the system can accommodate the specified operating voltage range and temperature constraints.

Digital To Analog Converters Part Context

This part belongs to the MCP47FVBXX family of single and dual-channel DACs. It shares core functionality with other resolutions in the series, such as the 10-bit MCP47FVB12 and 12-bit MCP47FVB22 variants. The '02' designation specifically indicates the dual-channel configuration with 8-bit resolution. It differs from the FEBx series by using volatile RAM instead of non-volatile EEPROM for data storage.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include MCP47FVB12-E/ST (10-bit) and MCP47FVB22-E/ST (12-bit). For non-volatile requirements, consider the MCP47FEB02-A2-E/ST. Ensure pinout and register compatibility when swapping between these variants.
