C4570C

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.
