Dual Operational Amplifier The LM358AN is a dual operational amplifier (op-amp) manufactured by STMicroelectronics (ST) and National Semiconductor (NS). 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)
- **Input Offset Voltage:** 2mV (typical), 7mV (maximum)
- **Input Bias Current:** 20nA (typical)
- **Input Offset Current:** 2nA (typical)
- **Common-Mode Rejection Ratio (CMRR):** 70dB (typical)
- **Supply Current per Amplifier:** 0.7mA (typical)
- **Gain Bandwidth Product:** 1MHz (typical)
- **Slew Rate:** 0.3V/µs (typical)
- **Operating Temperature Range:** 0°C to +70°C (commercial grade)
- **Package:** 8-pin PDIP (Plastic Dual In-line Package)
### **Descriptions:**
- The LM358AN is a low-power, dual operational amplifier designed for general-purpose applications.
- It features two independent op-amps in a single package, making it suitable for space-constrained designs.
- The device operates from a single power supply or dual supplies and is capable of driving loads down to ground (single-supply operation).
- It is internally frequency-compensated for stable operation in unity-gain configurations.
### **Features:**
- **Low Power Consumption:** Ideal for battery-operated applications.
- **Wide Supply Voltage Range:** Supports operation from 3V to 32V.
- **Large DC Voltage Gain:** 100dB (typical).
- **Low Input Offset Voltage and Current:** Ensures accuracy in signal conditioning.
- **Differential Input Voltage Range:** Equal to the supply voltage.
- **Output Voltage Swing:** Includes ground (0V) in single-supply operation.
- **Short-Circuit Protection:** Enhanced device reliability.
- **Internally Compensated:** No external components required for stability.
