In this detailed guide, we will delve into the key features and performance parameters of the LM358, helping you understand why it remains a popular choice among hobbyists and professionals alike.
General Specifications
The LM358 is a dual operational amplifier, meaning it contains two separate amplifiers within a single package. Here are some of its general specifications:
| Parameter | Value |
|---|---|
| Supply Voltage Range | 4V to 32V |
| Power Supply Current | 500渭A typ, 1mA max |
| Input Offset Voltage | 2mV typ, 10mV max |
| Input Bias Current | 50nA typ, 200nA max |
| Open-Loop Gain | 100dB typ, 160dB min |
| Output Voltage Swing | 0V to Vcc – 1.5V |
These specifications provide a basic understanding of the LM358’s capabilities and limitations. Now, let’s dive deeper into some of its key features.
Input and Output Characteristics
The LM358 features differential inputs, which allow for better common-mode rejection ratio (CMRR) and improved noise immunity. Here are some important input and output characteristics:
| Parameter | Value |
|---|---|
| Input Common-Mode Voltage Range | 0V to Vcc |
| Input Differential Voltage Range | 0V to Vcc |
| Output Current | 20mA typ, 40mA max |
| Output Resistance | 50惟 typ |
These characteristics make the LM358 suitable for a wide range of applications, including signal conditioning, filtering, and amplification.
Power Supply Rejection Ratio (PSRR)
The PSRR of an operational amplifier is a measure of its ability to reject noise and disturbances on the power supply line. The LM358 has a relatively high PSRR, which makes it less susceptible to power supply noise. Here are the PSRR specifications for the LM358:
| Parameter | Value |
|---|---|
| PSRR (0Hz to 10kHz) | 60dB typ, 80dB min |
| PSRR (10kHz to 100kHz) | 50dB typ, 70dB min |
This high PSRR ensures that the LM358 can maintain stable performance even in the presence of power supply noise.
Temperature Range and Stability
The LM358 is designed to operate over a wide temperature range, making it suitable for various environments. Here are the temperature specifications for the LM358:
| Parameter | Value |
|---|---|
| Operating Temperature Range | -40掳C to 85掳C |
| Storage Temperature Range | -65掳C to 150掳C
