NJU7077 Operational Amplifier with High RF Noise Immunity
It features a low input offset voltage (150µV max.), low temperature drift (0.5µV/°C typ.), low noise (10nV/√Hz typ.) and low bias current (1pA typ.). This makes it well-suited to sensor applications such as temperature sensors and weight sensors and for high precision current sensing amplifiers and current voltage converters.
It has Rail-to-Rail output and the output swing can reach 20 mV from the rails, while driving a 10kΩ load at 5V operation.
Due to the high-impedance CMOS structure, input is operable GND sense.
It also features improved RF noise immunity, allowing for easy mitigation of RF noise from devices.
