DATA SHEET BIPOLAR ANALOG INTEGRATED CIRCUIT 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 .

DATA SHEET BIPOLAR ANALOG INTEGRATED CIRCUIT 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 ORDERING INFORMATION Part Number Package μ PC4570C 8-pin plastic DIP (7.62 mm (300)) μ PC4570G2 8-pin plastic SOP (5.72 mm (225)) μ PC4570G2(5) 8-pin plastic SOP (5.72 mm (225)) EQUIVALENT CIRCUIT (1/2 Circuit) PIN CONFIGURATION (Top View) μ PC4570C, 4570G2 OUT1 1 1 –+ II1 2 I N1 3 8 V+ 7 OUT2 2 +– 6 II2 V+ R1 Q7 Q5 Q14 Q11 Q13 Q8 R7 Q16 II Q1 Q2 Q9 IN R6 R5 C2 R8 R9 Q12 Q15 Q6 Q3 Q4 Q10 OUT R2 C1 R3 R4 R10 D V− V− 4 5 I N2 The information in this document is subject to change without notice.

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.
