IC OPAMP GP 1 CIRCUIT 8DIP
The CA3140E is an integrated circuit, operating at supply voltage from 4V to 36V (either single or dual supply). This article is going to introduce pinout, circuit, applications, features, and more details about CA3140E.
CA3140E
| Descriptions |
| 1. The CA3140E BiMOS operational amplifiers feature gate-protected MOSFET (PMOS) transistors in the input circuit to provide very high input impedance, very low input current, and high-speed performance. |
| 2. The CA3140E operates at supply voltage from 4V to 36V (either single or dual supply). These operational amplifiers are internally phase compensated to achieve stable operation in unity gain follower operation |
| 3. CA3140E has an access terminal for a supplementary external capacitor if additional frequency roll-off is desired. Terminals are also provided for use in applications requiring input offset voltage nulling. |
| 4. The use of PMOS field-effect transistors in the input stage results in common-mode input-voltage capability down to 0.5V below the negative supply terminal, an important attribute for single-supply applications. |
| 5. The output stage uses bipolar transistors and includes built-in protection against damage from load terminal short-circuiting to either supply rail or to ground. |
