Intersil CA3130EZ Operational Amplifier 15MHz DIP-8 Package

The Intersil CA3130EZ is a 15MHz BiMOS operational amplifier that combines MOSFET input stages with CMOS output technology for single-supply and split-supply designs.

Overview

The CA3130EZ integrates gate-protected P-channel MOSFET (PMOS) transistors in its input circuit, delivering high input impedance and low input current. The device also provides superior speed performance. Its CMOS transistor pair at the output stage supports a wide output voltage swing, while the BiMOS architecture combines characteristics of both CMOS and bipolar transistors in a versatile component for electronic design.

Key Features

• Extended common-mode input-voltage range, reaching 0.5V below the negative supply rail
• Output voltage swing to within 10mV of either supply rail when driving high-impedance loads
• Rail-to-rail output behaviour that maximises dynamic range in low-voltage operations
• External phase compensation achieved with a single capacitor
• Terminals included for offset voltage adjustment and output stage strobing control

Specifications

• Gain bandwidth product: 15MHz
• Slew rate: 9V/µs (typical)
• Supply voltage range: 5V to 16V single supply, or ±2.5V to ±8V dual supply
• Dimensions (W x D x H): 3.3 x 1.5 x 4.3
• Weight: 0.833 gm
• Package: Industry-standard 8-pin DIP

Applications

Suited to single-supply applications, which are a critical requirement in many contemporary circuits, and to split-supply configurations. The extended input range and rail-to-rail output make it suitable for low-voltage operations.

The Intersil CA3130EZ is a practical choice for designers requiring a 15MHz operational amplifier with high input impedance and single-supply capability.
