What is the current delivery capability of a typical BUFFER amplifier that is part of an IC module, up to 30 volts?

The typical current delivery capability of a BUFFER amplifier within an IC module is often around 40 mA when operating at voltages up to 30 volts. This level of current is sufficient for driving various loads such as small transistors or other digital logic inputs while maintaining the integrity of the signal without degradation.

BUFFER amplifiers are designed to provide a high input impedance and a low output impedance, allowing them to effectively drive connected circuits without loading down the previous stage. The choice of 40 mA as a standard output capability aligns with common specifications found in many digital electronics applications, providing a good balance between performance and power consumption. This makes it versatile enough for different applications in digital circuits.

In the context of the question, the other values—20 mA, 30 mA, and 50 mA—are less commonly specified for standard BUFFER amplifiers in IC modules, as 40 mA is generally recognized as a typical figure that supports most general applications effectively.
