The CA3140A and CA3140 are integrated circuit operational amplifiers combining high voltage PMOS and bipolar transistors in a single chip. They offer high input impedance, low input current, and fast performance. With a supply voltage range of 4V to 36V, they’re internally compensated for stable operation in unity gain follower mode. They feature an access terminal for external capacitor frequency roll-off and input offset voltage nulling. Their PMOS input stage allows for common-mode input voltage down to 0.5V below the negative supply terminal, suitable for single supply applications. The output stage includes bipolar transistors and built-in protection against load short-circuiting. Designed for up to 36V operation, they’re versatile for various high-voltage applications.
