RS8414XP

Overview

The RS8414XP is a quad-channel CMOS operational amplifier manufactured by Runic Technology. It features rail-to-rail output capability and supports high-voltage operation up to 36V with a minimum supply of 3V. Key electrical parameters include a gain-bandwidth product of 1.2MHz, a slew rate of 0.67V/µs, and an input bias current of 1pA. The device offers an output current of 70mA per channel and total supply current of 150µA for all four channels. It exhibits an input offset voltage of 1.5mV and operates within a temperature range of -40°C to 125°C in a 14-SOIC package.

Feature Summary

• Rail-to-rail output performance enabling full signal swing near supply rails
• High voltage tolerance supporting single or dual supply systems up to 36V
• Unit-gain stability ensuring reliable operation in feedback configurations
• Ultra-low input bias current suitable for high-impedance sensor interfaces

Applications

• Photodiode amplification circuits
• Active filter designs
• Driving analog-to-digital converters
• General-purpose signal conditioning

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pinout compatibility and functional equivalence. Ensure the procurement source provides valid RoHS compliance documentation. Confirm that the delivered components match the 14-SOIC package dimensions specified in the technical data. Validate the part number against the manufacturer's current production status to avoid obsolete stock.

Selection Notes

Select this component when a quad-channel configuration is required alongside rail-to-rail output capabilities. The 1.2MHz bandwidth and 0.67V/µs slew rate suit moderate-speed applications rather than high-frequency signaling. The low 1pA input bias current makes it appropriate for interfacing with high-impedance sources. Consider the 14-SOIC package constraints for PCB layout requirements.

Part Context

This device belongs to the RS841x series from Runic Technology, which includes variants with different channel counts such as the RS8411BXF. The series is characterized by its CMOS architecture, offering a balance between speed and power consumption. The RS8414XP specifically integrates four independent amplifiers into a single compact surface-mount package.

Replacement Considerations

Cross-reference with other members of the RS841x family, such as the RS8411BXF, if channel count adjustments are permissible. Verify pinout compatibility before substituting with generic quad op-amps. No direct public substitute part numbers are confirmed in the provided documentation.
