The LM725/LM725A/LM725C are operational amplifiers featuring superior performance in applications where low noise, low drift, and accurate closed-loop gain are required. With high common mode rejection and offset null capability, it is especially suited for low level instrumentation applications over a wide supply voltage range.

The LM725A has tightened electrical performance with higher input accuracy and like the LM725, is guaranteed over a -55°C to +125°C temperature range. The LM725C has slightly relaxed specifications and has its performance guaranteed over a 0°C to 70°C temperature range.

Features

High open loop gain 3,000,000
Low input voltage drift 0.6 µV/°C
High common mode rejection 120 dB
Low input noise current 0.15 pA/SqrtHz#
Low input offset current 2 nA
High input voltage range ±14V
Wide power supply range ±3V to ±22V
Offset null capability
Output short circuit protection
