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
