Op-Amp (15MHz) CA3130

The Op-Amp (15MHz) CA3130 is a BiMOS operational amplifier that combines a MOSFET input stage with a CMOS output stage. It has an extremely high input impedance, input current in the picoamp range, an output that can swing to either supply rail and a gain-bandwidth of 15 MHz. It is well suited to single-supply circuits, sensor buffers, sample-and-hold stages and comparators.

Op-Amp (15MHz) CA3130 Specifications

• Type: BiMOS op-amp, MOSFET inputs and CMOS output
• Gain-bandwidth: 15 MHz
• Supply voltage: 5 V to 16 V single, or ±2.5 V to ±8 V dual
• Input impedance: about 1.5 TΩ (typical)
• Input current: about 5 pA (typical, at 15 V)
• Input range: common-mode range includes the negative supply rail
• Output: CMOS stage, swings close to both supply rails
• Compensation: external, one capacitor between pins 1 and 8; pin 8 can also be used for strobing
• Pins: 8

Op-Amp (15MHz) CA3130 Applications

• High-impedance buffers for sensors and probes
• Sample-and-hold circuits and peak detectors
• Single-supply comparators and voltage followers
• Long-period timers and oscillators using large resistor values
• Active filters and instrumentation projects

What's in the Box

• 1 × CA3130 op-amp IC

Tip: The CA3130 is not internally compensated, so for unity-gain or low-gain circuits fit the compensation capacitor between pins 1 and 8 as shown in the datasheet. Keep the total supply at 16 V or less; it cannot run from ±15 V like a 741.
