Description
The μPC4072MF-DAA is a J-FET input operational amplifier.
This product is designed as low noise version of the μPC4082.
The features of the μPC4072MF-DAA are more improved input equivalent noise voltage, input offset voltage and input bias current than those of μPC4082.
By these features, the μPC4072MF-DAA is excellent choice for wide variety of applications including audio preamplifier and active filter.
Features
• Input Offset Voltage: ±2 mV (TYP.
) • Input Bias Current :30 pA (TYP.
) • High Slew Rate: 13 V/μs (TYP.
) • Unity Gain Frequency: 3 MHz (TYP.
) • Low noise: 17 nV/√Hz (TYP.
) @ f = 1 kHz • Internal frequency compensation • Output short circuit protection • High input impedance: J-FET Input stage
