High Speed Single Supply Operational Amplifier

Download Datasheet

  • Description

    The NJM842 are high speed single supply operational amplifier. These amplifiers feature is low-offset voltage, low-offset voltage drift, 8.5V/µs slew rate, 3.5MHz gain bandwidth and unity-gain stable (CL=1000pF). As a further feature, wide operation voltage range and wide operation temperature range are suitable for power supply unit, general-purpose inverters and high performance industrial equipment.
