NJU7066 PRECISION, LOW NOISE, RAIL-TO-RAIL OUTPUT, EXCELLENT EMI IMMUNITY, CMOS OPERATIONAL AMPLIFIERS FEATURES DESCRIPTION High Precision The NJU7066 is a dual channel, precision, low-noise, Low Input Offset Voltage 500V max. rail-to-rail output CMOS operational amplifiers. Low Offset Voltage Drift 0.5V/C typ. The combination of these specifications makes the devices Low Noise 10nV/Hz typ. well-suited for sensor applications such as temperature Low Input Bias Current 1pA typ. sensors, weight sensors, high-precision current sensing Rail-to-Rail Output amplifiers, and current-voltage converters. + R =10k 0.02V to 4.98V typ. (V =5V) L The output swing can reach 20 mV from the rails while + R =600 0.08V to 4.92V typ. (V =5V) L driving a 10k load (at 5V operation). Input voltage Ground Sensing includes ground, enabling direct sensing near ground. Integrated EMI Filter EMIRR=59dB typ. f=900 MHz Operating Voltage 2.2V to 5.5V The NJU7066 have high EMI immunity to reduce Unity-Gain Stable malfunctions, making them ideal for EMI-sensitive Package applications.
