BIPOLAR ANALOG INTEGRATED CIRCUIT
µPC4556
HIGH PERFORMANCE DUAL DECOMPENSATED
OPERATIONAL AMPLIFIER
DESCRIPTION
The µPC4556 is a dual operational amplifier which features further advanced A.C. performance than that of the µPC4558.
Decompensation characteristic guarantees 20MHz gain-bandwidth product higher than 20 dB. Also featured are low input
noise and high output drive capability making this device the optimum choice for audio application.
FEATURES
• Gain bandwidth products: 20 MHz (Av ≥ 20 dB)
• High slew rate: 5 V/µs
• Low input noise voltage: 6 µVp-p
• Internal frequency compensation (Av ≥ 20 dB)
