μ PC4570
ULTRA LOW-NOISE, WIDEBAND, DUAL OPERATIONAL AMPLIFIER
DESCRIPTION The μ PC4570 is an ultra low-noise, wideband high slew-rate, dual operational amplifier. Input equivalent noise is three times better than the conventional 4558 type op-amps. The gain bandwidth products and the slew-rate are seven times better than 4558. In spite of fast AC performance, the μ PC4570 is extremely stable under voltage-follower circuit conditions. Supply current is also improved compared with conventional wideband op-amps. The μ PC4570 is an excellent choice for pre-amplifiers and active filters in audio, instrumentation, and communication circuits.
FEATURES • Ultra low noise: en = 4.5 nV/√Hz • High slew rate: 7 V/μs • High gain bandwidth product: GBW = 15 MHz at 100 kHz • Internal frequency compensation

Notes 1. Reverse connection of supply voltage can cause destruction. 2. The input voltage should be allowed to input without damage or destruction. Even during the transition period of supply voltage, power on/off etc., this specification should be kept. The normal operation will establish when the both inputs are within the Common Mode Input Voltage Range of electrical characteristics. 3. This specification is the voltage which should be allowed to supply to the output terminal from external without damage or destruction. Even during the transition period of supply voltage, power on/off etc., this specification should be kept. The output voltage of normal operation will be the Output Voltage Swing of electrical characteristics. 4. Thermal derating factor is −5.0 mW/°C when operating ambient temperature is higher than 55°C. 5. Thermal derating factor is −4.4 mW/°C when operating ambient temperature is higher than 25°C. 6. Pay careful attention to the total power dissipation not to exceed the absolute maximum ratings, Note 4 and Note 5.
