Description :

The NJM2749/2749A is a Precision dual JFET input operational amplifier which includes low input offset voltage: 0.8mV (typ) / 2.5mV (max) and 6µV/°C typical offset drift. The NJM2749A is guaranteed 20µV/°C maximum offset drift to perform a 100% tested. The NJM2749/2749A have the following features: low bias current of 50pA (typ), high slew rate of 13V/µs (typ).These features are suitable for signal processing amplifiers of instrumentation, measurement and industrial applications such as sensor amplifier, current sensing and sample-and-hold circuit.
