A new two-channel analog front end promises to eliminate long-standing microphone and line-level trade-offs by capturing everything from whisper-quiet signals to hot studio outputs on a single chip.

The single op-amp differential amplifier shown in Figure 1 is often used as an audio balanced line receiver. Obtaining high common-mode rejection is a critical requirement that requires four ...

The circuit was designed for providing a microphone line with a balance input signal to improve the quality of sound with sufficient gain and filter. NE5532 – an internally compensated low noise dual ...
