NJM2749/2749A
Low Offset, Low Drift Dual JFET Input Operational Amplifier
■GENRRAL 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.
