Overview
The LM301ADT is a general-purpose operational amplifier produced by STMicroelectronics. It is part of the LM101A/LM201A/LM301A series, known for their improved performance over earlier industry standards. The LM301A is specifically designed to operate within a temperature range of 0°C to +70°C, making it suitable for a variety of applications where moderate temperature stability is required.
This amplifier features advanced processing techniques that significantly reduce input currents and improve temperature drift characteristics. It offers overload protection on both the input and output, prevents latch-up when the common-mode range is exceeded, and is free from oscillations with compensation achievable using a single 30pF capacitor.
