The single-chip, monolithic integrated circuits CA3140A and CA3140 provide the advantages of both high-voltage PMOS and high-voltage bipolar transistors. The input circuit of the CA3140 and CA3140A BiMOS operational amplifiers uses gate-shielded MOSFET transistors to provide extremely high input impedance, extremely low input current, and high-speed performance.
The benefits of high-voltage PMOS and bipolar transistors are combined onto a single monolithic chip in operational amplifiers like the CA3140A and CA3140. The gate-protected MOSFET transistors used in the input circuit of the CA3140 and CA3140A BiMOS operational amplifiers provide extremely low input current, exceptionally high input impedance, and high-speed performance.
The input stage’s common mode input voltage capability can be as low as 0.5V below the negative supply terminal thanks to using PMOS field effect transistors, a crucial feature for single supply applications. The output stage, which uses bipolar transistors and has built-in protection against short circuit damage from the load terminal to the supply rail or the ground, is likewise protected against short circuit damage. It is designed for the CA3140 and CA3140A to operate at supply voltages up to 36V (or about 18V).
Operational amplifiers are useful in various applications, and the CA3140EZ is one such device. These are a few of its main characteristics:
Overall, the high-performance operational amplifier CA3140EZ is a good choice for various applications. It is a popular option for many circuits due to its high input impedance, low input bias current, low offset voltage, high output current, and wide supply voltage range.
The CA3140 uses a novel design based on the PMOS Bipolar technology to create a wide dynamic range of input and output characteristics with the most desirable high input impedance characteristics. Operation with a single supply down to 4V is possible thanks to the complementarity between the input common-mode voltage range and output swing capabilities.
This device is suitable for various single supply applications due to the wide dynamic range of these parameters, including those where the output signal’s phase sense must be maintained when one input is driven below Terminal 4’s potential, a crucial factor in comparator applications.
