- **Power Supply Rejection Ratio (PSRR):** 120dB (typical)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
- The ICL7650 is a chopper-stabilized operational amplifier designed for high-precision applications.  
- It features extremely low input offset voltage and drift, making it suitable for DC amplification and instrumentation.  
- The chopper stabilization technique minimizes long-term drift and noise.  

### **Features:**  
- **Ultra-Low Offset Voltage:** Ensures high accuracy in DC applications.  
- **Low Input Bias Current:** Reduces errors in high-impedance circuits.  
- **High CMRR and PSRR:** Enhances performance in noisy environments.  
- **Wide Supply Voltage Range:** Supports operation from ±5V to ±8V.  
- **Stable Over Temperature:** Low drift ensures consistent performance.  

This information is based on TI's documented specifications for the ICL7650.
