CA3130 CMOS Operational Amplifier [Original]

CA3130 CMOS Operational Amplifier

The CA3130 is a CMOS Operational Amplifier. It integrates CMOS and bipolar transistor technologies. The input stage uses gate-protected P-Channel MOSFETs. This provides 1.5 TΩ input impedance and 5 pA input current. The common-mode input-voltage range extends 0.5V below the negative supply rail. A CMOS output stage enables rail-to-rail signal swing, within 10mV of either supply rail. It operates with a 4 MHz gain bandwidth product and 10 V/µs slew rate. The CA3130 supports both dual (±2.2V to ±8V) and single (4.5V to 16V) supply designs.
