Overview
The LM224APT is a low-power, quad operational amplifier produced by STMicroelectronics. It consists of four independent, high-gain operational amplifiers with internal frequency compensation. These amplifiers can operate from a single power supply over a wide range of voltages (3 V to 30 V) or from dual supplies (±1.5 V to ±15 V), making them versatile for various applications. The LM224APT is packaged in a TSSOP14 (thin shrink small outline package) and is suitable for industrial environments with an operating temperature range of -40 °C to 105 °C.
