New Japan Radio NJM2748A
NJM2748/2748A
Low Offset, Low Drift single JFET Input
Operational Amplifier
GENERAL DESCRIPTION
The NJM2748/2748A is a Precision dual JFET input operational
amplifier which includes low input offset voltage: 0.7mV (typ) / 2.0mV
(max) and 6µV/°C typical offset drift.
The NJM2748A is guaranteed 20µV/°C maximum offset drift to
perform a 100% tested.
The NJM2748/2748A 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.

NJM2748/2748A
(Note4) These devices are measured under three temperature conditions of Ta=40°C, +25°C, +85°C.
(Note5) Temperature coefficient is calculated by specified change in offset voltage. (Changes Ta=+25°C to 40°C and Ta=+25°C to +85°C)
NJM2748A is guaranteed maximum specification because these are 100% tested to operating temperature range.
NJM2748 is guaranteed only typical specification.
(Note6) Written by the absolute rate.
(Note7) Measured at VICM=0V
(Note8) CMR is calculated by specified change in offset voltage. (VICM=0V to +10V and VICM=0V to 10V)
(Note9) SVR is calculated by specified change in offset voltage. (V+/V=±6V to ±16V)
(Note10) VICM is input common mode voltage when tested meets specified change in offset voltage is CMR76dB.
(A point of reference is offset voltage of VICM=0V)
