CA3130
BiMOS Operational Amplifier
with MOSFET Input/CMOS Output
April 1993
Features
Description
• 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
CA3130A and CA3130 are integrated-circuit operational
amplifiers that combine the advantage of both CMOS and
bipolar transistors on a monolithic chip.
Gate-protected p-channel MOSFET (PMOS) transistors are
used in the input circuit to provide very-high-input imped-
ance, very-low-input current, and exceptional speed perfor-
mance. The use of PMOS field-effect transistors in the input
stage results in common-mode input-voltage capability down
to 0.5 volt below the negative-supply terminal, an important
attribute in single-supply applications.
• Ideal for Single-Supply Applications
• Common-Mode Input-Voltage Range Includes Nega-
tive 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
A complementary-symmetry MOS (CMOS) transistor-pair,
capable of swinging the output voltage to within 10 millivolts
of either supply-voltage terminal (at very high values of load
impedance), is employed as the output circuit.
Applications
• Ground-Referenced Single Supply Amplifiers
• Fast Sample-Hold Amplifiers
• Long-Duration Timers/Monostables
The CA3130 Series circuits operate at supply voltages rang-
ing from 5 to 16 volts, or ±2.5 to ±8 volts when using split
supplies. They can be phase compensated with a single
external capacitor, and have terminals for adjustment of off-
set voltage for applications requiring offset-null capability.
Terminal provisions can also made to permit strobing of the
output stage.
• High-Input-Impedance Comparators
(Ideal Interface with Digital CMOS)
• High-Input-Impedance Wideband Amplifiers
The CA3130A offers superior input characteristics over
those of the CA3130.
• Voltage Followers (e.g. Follower for Single-Supply D/A
Converter)
• Voltage Regulators (Permits Control of Output Voltage
Down to Zero Volts)
• Peak Detectors
• Single-Supply Full-Wave Precision Rectifiers
• Photo-Diode Sensor Amplifiers
