Dual Operational Amplifier The LM358A is a dual operational amplifier (op-amp) manufactured by ON Semiconductor. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:
### **Specifications:**
- **Supply Voltage Range:** 3V to 32V (or ±1.5V to ±16V for dual supply)
- **Low Supply Current:** 700 µA per amplifier (typical)
- **Input Offset Voltage:** 2 mV (typical), 7 mV (maximum)
- **Input Bias Current:** 20 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:** Equal to the supply voltage
- **Output Voltage Swing:** Rail-to-rail (near ground and V+)
- **Operating Temperature Range:** −40°C to +125°C
### **Descriptions:**
- The LM358A is a low-power, dual-channel operational amplifier designed for general-purpose applications.
- It is an improved version of the standard LM358, offering better performance in terms of offset voltage and power consumption.
- Suitable for battery-powered devices, transducer amplifiers, and DC gain blocks due to its wide supply voltage range and low current consumption.
### **Features:**
- **Low Power Consumption:** Ideal for portable and battery-operated systems.
- **Wide Supply Voltage Range:** Operates from a single supply (3V–32V) or dual supplies (±1.5V–±16V).
- **Rail-to-Rail Output Swing:** Maximizes dynamic range in single-supply applications.
- **ESD Protection:** Improved robustness with ESD clamp diodes on inputs and outputs.
- **Unity-Gain Stable:** No external compensation required.
- **Pb-Free Packages Available:** Compliant with environmental regulations.
