LM725 is an operational amplifier produced by National Semiconductor Corporation. It has high open loop gain, low input voltage drift, high common mode rejection ratio, low input noise current, low input offset current, high input voltage range, wide power supply range, offset elimination function and output short circuit protection function. It is suitable for low level instrumentation applications.
The LM725, LM725A, and LM725C are operational amplifiers designed for low noise, low drift, and accurate closed-loop gain applications. They feature high common mode rejection and offset null capability, making them suitable for low-level instrumentation over a wide supply voltage range. The LM725A offers tightened electrical performance with higher input accuracy, while the LM725C has slightly relaxed specifications.
