DATA SHEET
BIPOLAR ANALOG INTEGRATED CIRCUIT
µPC4558
HIGH PERFORMANCE DUAL OPERATIONAL AMPLIFIER
DESCRIPTION
The µPC4558 is a dual type operational amplifier having internal phase compensating circuits, its electrical
characteristics features higher speed, broader bandwidth, and lower noise compared with such conventional general
purpose operational amplifier as µPC741.
Therefore, application to active filters, audio amplifiers, VCO, etc. can be realized with simple circuit composition.
FEATURES
• Internal frequency compensation
• Low noise
• Output short circuit protection
