UPC4570

DATA SHEET BIPOLAR ANALOG INTEGRATED CIRCUIT µPC4570 ULTRA LOW-NOISE, WIDEBAND, DUAL OPERATIONAL AMPLIFIER DESCRIPTION The µPC4570 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 µPC4570 is extremely stable under voltage-follower circuit conditions. Supply current is also improved compared with conventional wideband op-amps. The µPC4570 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 µPC4570C 8-pin plastic DIP (7.62 mm (300)) µPC4570G2 8-pin plastic SOP (5.72 mm (225)) µPC4570HA 9-pin plastic slim SIP EQUIVALENT CIRCUIT (1/2 Circuit) V+ R1 Q7 Q5 Q14 Q11 II Q1 Q2 Q13 Q8 Q9 R7 Q16 IN R5 R6 C2 R8 R9 Q12 Q15 Q6 Q3 Q4 Q10 OUT R2 C1 R3 R4 R10 D V− V+ OUT1 I I1 I N1 V– I N2 I I2 OUT2 V+ PIN CONFIGURATION (Top View) µPC4570C, 4570G2 OUT1 1 I I1 2 1 –+ I N1 3 8 V+ 7 OUT2 2 +– 6 I I2 V– 4 5 IN2 µPC4570HA 12 –+ +– 123456789 The information in this document is subject to change without notice.
