Composite Amplifier Topology
A Composite Amplifier Topology is implemented in the CH-Amp. Composite op-amp brings the best of both worlds with excellent DC and AC characteristics. These amplifiers offer several advantages over other types of amplifiers.
Power amplifiers typically use thermal feedback loops, thus causing serious errors while driving heavy loads. These errors occur due to self-heating. The use of the composite can remove such errors and improves the performance of the circuitry. The composite amplifiers also offer better DC output-offset. The excess of the load placed on the output transistors does not affect offset voltage.
