Consumer

Description
The NJM844 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 (C_L=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.

Applications
- Motor, Inverter Current Sense Application
- Power Supply Application
- Buffer Application Amplifier
- Active filter
