CA3130 BiMOS Op-Amp

CA3130A and 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. The CA3130 Op-amp operate at supply voltages ranging from 5V to 16V, (±2.5V to ±8V). They can be phase compensated with a single external capacitor, and have terminals for adjustment of offset voltage for applications requiring offset-null capability. Terminal provisions are also made to permit strobing of the output stage. The CA3130A offers superior input characteristics over those of the CA3130.

Features of CA3130 BiMOS Op-Amp

  • MOSFET Input Stage Provides :

                    - Very High ZI = 1.5 TΩ (1.5 x 1012Ω) (Typ)

                    - Very Low II  = 5pA (Typ) at 15V Operation
                                               2pA (Typ) at 5V Operation

  • 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

Applications of CA3130 BiMOS Op-Amp

  • Ground-Referenced Single Supply Amplifiers

  • Fast Sample-Hold Amplifiers

  • Long-Duration Timers/Monostables

  • High-Input-Impedance Comparators (Ideal Interface with Digital CMOS)

  • High-Input-Impedance Wideband Amplifiers

  • Voltage Followers (e.g. Follower for Single-Supply D/A Converter)

  • Voltage Regulators (Permits Control of Output Voltage Down to 0V)

  • Peak Detectors

  • Single-Supply Full-Wave Precision Rectifiers

  • Photo-Diode Sensor Amplifiers
