Description and Introduction

Low Power Quad Operational Amplifier The LM124 from STMicroelectronics is a low-power quad operational amplifier. Below are its specifications, descriptions, and features based on factual data:

### **Specifications:**  
- **Supply Voltage Range:** 3V to 32V (or ±1.5V to ±16V for dual supply)  
- **Low Supply Current (per amplifier):** 375 µA (typical)  
- **Input Offset Voltage:** 2 mV (typical), 7 mV (max)  
- **Input Bias Current:** 20 nA (typical)  
- **Input Offset Current:** 3 nA (typical)  
- **Gain Bandwidth Product:** 1 MHz (typical)  
- **Slew Rate:** 0.3 V/µs (typical)  
- **Common-Mode Input Voltage Range:** Includes ground (V−)  
- **Differential Input Voltage Range:** Up to supply voltage  
- **Output Voltage Swing:** Rail-to-rail (close to supply rails)  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions:**  
- The LM124 consists of four independent, high-gain, internally frequency-compensated operational amplifiers.  
- Designed for single-supply operation but can also operate from split supplies.  
- Suitable for battery-powered applications due to low power consumption.  
- Internally compensated for unity-gain stability.  

### **Features:**  
- **Low Power Consumption:** Ideal for portable and battery-operated devices.  
- **Wide Supply Voltage Range:** Supports both single and dual supply configurations.  
- **High Input Impedance:** Minimizes loading effects.  
- **ESD Protection:** Improved robustness against electrostatic discharge.  
- **Short-Circuit Protection:** Enhanced reliability in harsh conditions.  
- **Direct Replacement:** Compatible with industry-standard LM124/LM224/LM324 devices.  

This information is sourced from the official STMicroelectronics datasheet for the LM124.
