J-FET Input LOW-NOISE QUAD OperationAL AMPLIFIER

The μPC4074 is a J-FET input operational amplifier. This product is designed as low noise version of the μPC4084. The features of the μPC4074 are more improved input equivalent noise voltage, input offset voltage and input bias current than those of μPC4084. By these features, the μPC4074 is excelle ? Low noise: en = 17 nV/√Hz (TYP.)\n? Very low input bias and offset currents\n? Output short circuit protection\n? High input impedance...J-FET Input stage\n? Internal frequency compensation\n? High slew rate...13 V/μs (TYP.);
