General Description

The NJU7066 is a dual channel, precision, low-noise, rail-to-rail output CMOS operational amplifiers. The combination of these specifications makes the devices well-suited for sensor applications such as temperature sensors, weight sensors, high-precision current sensing amplifiers, and current-voltage converters. The output swing can reach 20 mV from the rails while driving a 10kΩ load (at 5V operation). Input voltage includes ground, enabling direct sensing near ground. The NJU7066 have high EMI immunity to reduce malfunctions, making them ideal for EMI-sensitive applications.
