The LM324NG is a non-inverting low power quad-channel operational amplifier (op amp) designed for use in a variety of general purpose applications. It can be used in a wide range of instrumentation and buffering applications. This op amp has an input range of -36V to +36V and an output current of 25mA per channel. The LM324NG is based on the popular LM324 family of op amps, which have been a mainstay of the instrumentation and buffering industry for decades. It can be used for voltage and current amplification, signal conditioning, filtering, analogue-to-digital and digital-to-analogue conversion, and active data transmission.

The LM324NG features four operational amplifiers operating from a single supply voltage of +/- 5V to +/- 36V. Each op amp has an individual output, allowing for more complex signal conditioning between each amplifier. It offers high-speed performance with unity-gain bandwidth of 8.5MHz, low input bias current of 1.5pA and an input offset voltage of only 2mV. It also offers low distortion in the output stage, with a maximum output of 20mA.

LM324NG can be used in many different applications, such as measuring temperature, voltage, current, pressure, and sound. Its typically used in audio amplifiers, test instruments, filter and signal replacements, active filters, power supply sensors, low power instrumentation, and data acquisition systems. It is most often used as a voltage gain, buffer amplifier, differential or summing amplifier, and instrumentation amplifier.

The LM324NG features an active low pass filter to reduce distortion and noise. This active low pass filter can be configured to have an adjustable cut off frequency, meaning that a variety of filtering responses can be achieved. This is especially useful for applications like audio equalization, where powerful accurate equalizers can be achieved through low noise and distortion performance.

The LM324NG also features an output stage that can be configured to have a range of response curves, from single-side band (SSB), balanced, active low threshold (AL), to frequency-shaping and auto-balancing. The response curves and output levels of the output stage can be dynamically adjusted without the need for external components and boards.

The working principle behind the LM324NG is simple and effective. A differential input signal is applied to the two inputs of the op amp, which then amplifies the signal and outputs a single, amplified output. The output stage is then used to reduce distortion and noise, and the output level adjusted for gain or attenuation. The output stage of the LM324NG can be set to three different modes: a single-sideband (SSB) mode, a balanced mode and an active low threshold (AL) mode. Each of these modes has its own output characteristics and levels.

The LM324NG is a versatile and powerful op amp and its wide range of applications across a variety of industries make it an invaluable tool. Its low quiescent current, high performance and adjustable response curves make it an ideal choice for many different types of applications, from audio to instrumentation. Whether it’s amplifying, filtering or converting, the LM324NG has got you covered.
