The CA3140A and CA3140 are integrated circuit operational amplifiers combining high voltage PMOS and bipolar transistors on a single chip. These BiMOS amplifiers feature gate-protected PMOS transistors in the input circuit, ensuring high input impedance, low input current, and fast performance. They operate within a 4V to 36V supply voltage range for single and dual supply setups. Internally phase-compensated, they provide stable unity gain follower operation and offer access terminals for additional frequency roll-off with external capacitors. With PMOS transistors in the input stage, they support common mode input voltage down to 0.5V below the negative supply terminal, ideal for single supply applications. The output stage includes built-in protection against load terminal short-circuiting. Rated for operation up to ±18V, they serve various high-voltage applications efficiently.
