Description
The LM324N is a quadruple operational amplifier (op-amp) from Texas Instruments (TI). This internal-frequency-compensated op-amp features large DC voltage gain, wide bandwidth, and a low power supply current drain. It operates with a single supply voltage of 3V to 32V or dual supplies of ±1.5V to ±16V.
The LM324N provides advantages such as eliminating the need for dual supplies, allowing direct sensing near ground and Vout, and being compatible with all forms of logic. Its power drain is suitable for battery operation, making it a versatile component for various applications.
Features
According to the product information, the LM324N features include:
- Internally frequency compensated for unity gain
- Large DC voltage gain of 100 dB
- Wide bandwidth (unity gain) of 1 MHz (temperature-compensated)
- Wide power supply range: single supply (3V-32V), or dual supplies (±1.5V to ±16V)
- Very low supply current drain (700 µA) - essentially independent of supply voltage
- Low input biasing current (45 nA) and offset voltage (2 mV)
- Input common-mode voltage range includes ground, and differential input voltage range equal to the power supply voltage
- Large output voltage swing (0V to V+ - 1.5V)
These features provide advantages such as eliminating the need for dual supplies, allowing direct sensing near GND and VOUT, and being compatible with all forms of logic.
