Operational Amplifier, Quad, 4 Channels, 1.3MHz, 0.4V/µs, ±1.5V to ±15V, SOIC,

The STMICROELECTRONICS LM324ADT is a low-power quad operational amplifier designed for a wide range of applications. It integrates four independent, high-gain amplifiers with internal frequency compensation, ensuring stable operation without external components. The device can operate from a single power supply over a broad voltage range or from split supplies, with the low supply current drain remaining independent of the supply voltage magnitude.

This operational amplifier features an input common-mode voltage range that includes ground, enabling single-supply operation from +3V to +30V and dual-supply operation from ±1.5V to ±15V. It delivers a typical gain bandwidth product of 1.3MHz and a slew rate of 0.4V/µs, making it suitable for general-purpose signal conditioning, filter circuits, and control systems. With a typical input bias current of 20nA and an input offset voltage of 2mV, it offers reliable performance in precision applications.

Housed in an SO14 (SOIC) package with 14 pins and surface-mount mounting, the LM324ADT operates over a temperature range of 0°C to 70°C, ensuring suitability for standard industrial and consumer environments. Its low power consumption, with a typical supply current of 0.7mA at +5V, enhances energy efficiency in battery-powered designs.

The quad amplifier configuration provides design flexibility, allowing multiple stages to be integrated into a single device, reducing board space and component count. With a typical common mode rejection ratio of 80dB, it effectively suppresses common-mode noise, improving signal integrity. This operational amplifier is a versatile choice for engineers seeking a dependable, low-power solution for analog signal processing tasks.
