CA3130 CMOS Operational Amplifier

Description of product

CA3130 CMOS Op-Amp (CA3130E)
 
Feature
  • Ideal for Single-Supply Applications
  • Common-Mode Input-Voltage Range Includes Negative Supply Rail; Input Terminals can be Swung 0.5V Below Negative Supply Rail
  • CMOS Output Stage Permits Signal Swing to Either (or both) Supply Rails
General Description
CA3130 are op amps that combine the advantage of both CMOS and bipolar transistors.
 
Gate-protected P-Channel MOSFET (PMOS) transistors are used in the input circuit to provide very-high-input impedance, very-low-input current, and exceptional speed performance. The use of PMOS transistors in the input stage results in common-mode input-voltage capability down to 0.5V below the negative-supply terminal, an important attribute in single-supply applications.
 
A CMOS transistor-pair, capable of swinging the output voltage to within 10mV of either supply-voltage terminal (at very high values of load impedance), is employed as the output circuit.
