RS6334XQ

Overview

The RS6334XQ is a quad CMOS operational amplifier manufactured by Runic Technology, housed in a 14-TSSOP package. It features rail-to-rail input and output capabilities with a gain bandwidth product of 1.1 MHz and a slew rate of 0.5V/µs. Key electrical specifications include an input bias current of 1 pA, a supply current of 58µA per channel, and an output current of 55 mA per channel. The device operates within a temperature range of -40°C to 125°C, with input offset voltage values documented between 25 µV and 600 µV depending on specific grading.

Feature Summary

• Rail-to-rail input and output signal swing capability
• Ultra-low input bias current for high-impedance sources
• Quad configuration in a compact surface-mount package

Applications

• Bridge transducer signal conditioning
• Thermocouple amplification circuits
• Biopotential electrode interfaces in ECG/EEG systems

Procurement Notes

Verify the exact input offset voltage grade required for your application, as datasheets indicate variations (e.g., 25 µV vs 600 µV). Confirm that the 14-TSSOP package dimensions align with your PCB footprint. Ensure the operating temperature range meets your environmental specifications. Cross-reference the manufacturer's latest documentation for any pinout or electrical characteristic updates before finalizing procurement.

Selection Notes

Select this component when a quad amplifier with rail-to-rail performance is needed. The low input bias current makes it suitable for high-impedance sensor interfaces. Consider the 1.1 MHz bandwidth sufficient for low-frequency precision applications. Verify that the 55 mA output drive capability meets load requirements. Compare against other quad op-amps if higher speed or lower noise is required.

Part Context

This part belongs to the RS6334 series of rail-to-rail I/O CMOS operational amplifiers produced by Runic Technology. The series includes single, dual, and quad variants. The RS6334XQ specifically denotes the quad-channel version. These amplifiers are designed for general-purpose analog signal processing where low power consumption and wide common-mode range are prioritized over high-speed performance.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Consult the manufacturer's official documentation for recommended equivalents or cross-reference with industry-standard quad rail-to-rail op-amps if compatibility allows.
