What makes ERCO special

First of all ERCO is in many ways similar to OOR, but because it has a built in DAC, some design aspects needed a different approach. We decided on the IC based headphone amplifier, however it is not some off the shelf solution. ERCO has a composite topology amplifier, which means it has two IC amplifiers in one feedback loop. One of them acts as a buffer with its own feedback loop. This is a fast power op-amp which can …    Download the full white paper to read all about ERCO.
