CA3130 CMOS Op-Amp IC

The CA3130 is an op amp that blends CMOS and bipolar transistor advantages. It uses gate-protected PMOS transistors in the input circuit for high input impedance, low input current, and speed. It allows common-mode input down to 0.5V below the negative supply in single-supply setups. The output circuit employs a CMOS transistor pair for voltage swing near supply rails. Operating voltages range from 5V to 16V. It’s phase-compensatable with an external capacitor, has offset voltage adjustment terminals, and strobing capability. The CA3130A offers enhanced input characteristics.

Key Features:

• High input impedance (1.5 TΩ)
• Low input current (5pA at 15V, 2pA at 5V)
• Suitable for single-supply applications
• Wide common-mode input range
• CMOS output for full swing
• RoHS compliant

Please note that there’s a missing detail in the text: the part where it mentions “Pb-Free Plus Anneal Available” typically refers to the RoHS compliance and lead-free package options.
