High-Precision, Low-Noise, Quad CMOS Operational Amplifier
The RS8564XQ is a quad low-noise CMOS operational amplifier developed by RUNIC, designed for high-precision analog signal processing across industrial, medical, and instrumentation applications. Positioned as a performance-competitive yet cost-effective alternative to Analog Devices’ AD8618ARUZ, the RS8564XQ offers comparable electrical specifications while delivering enhanced system-level advantages.
| Parameter | RS8564XQ | AD8618ARUZ |
|---|---|---|
| Channels | 4 | 4 |
| Input Offset Voltage (Typ / Max) | 0.2 mV / 1 mV | 0.4 mV / 2 mV |
| Input Bias Current (Typ) | ±0.5 pA | ±1 pA |
| Voltage Noise Density @ 1kHz | 8 nV/√Hz | 8 nV/√Hz |
| Slew Rate | 10 V/μs | 5 V/μs |
| Gain Bandwidth Product | 20 MHz | 23 MHz |
| Supply Voltage Range | 2.5 V to 5.5 V | 2.7 V to 5.5 V |
| Supply Current (Typ, Total for 4 op-amps) | 2.4 mA | 3.2 mA |
| Rail-to-Rail Input/Output | ✅ Yes | ✅ Yes |
| Operating Temperature Range | –40°C to +125°C | –40°C to +125°C |
📌 Advantages of RS8564XQ:
Lower input offset voltage for higher accuracy
Faster slew rate = better dynamic response for pulse and switching signals
Lower total power consumption per quad channel
Broader input voltage range starts at 2.5 V for better low-voltage operation

💡 Design Flexibility:
The RS8564XQ is pin-to-pin compatible with AD8618ARUZ, allowing direct drop-in replacement without PCB redesign. This is ideal for OEMs looking for qualified second-source alternatives or seeking cost optimization in mass production.
🔍 Recommended for:
High-speed analog signal processing
Medical instrumentation and diagnostics
Data acquisition front ends
Active filters and high-impedance buffering
Portable, battery-powered devices requiring high precision and low power
⚡ Why RS8564XQ Stands Out:
📉 Reduced offset and bias: improves DC accuracy
🔋 Lower current draw: extends battery life in portable systems
🚀 Improved slew rate: ideal for high-speed sampling systems
💰 Lower cost with no compromise in quality: great price-to-performance ratio
The RS8564XQ from XINLUDA offers a high-performance, low-power, cost-effective solution in the quad op-amp category. Compared to the AD8618ARUZ, it delivers:
✅ Superior DC precision
✅ Faster signal response
✅ Lower power consumption
✅ Excellent noise characteristics
✅ Pin compatibility and high availability
This makes the RS8564XQ an ideal substitute or upgrade path in systems where accuracy, responsiveness, and efficiency are key requirements.\
