The TS5510 two-channel analog front end from Triad Semiconductor is a mixed-signal IC designed to handle both low-level microphone inputs and high-level line signals within a single input stage for professional and prosumer audio systems. Based on a current-conveyor architecture, the device supports a total input capture range of 156 dB, greater than 90 dB […]

Avoid ground loops in mixed-signal circuits, part 2
Picking up where we left off in Part 1, we need to explore some methods to mitigate problems caused by unpredictable ground currents. Let’s start with some simplification, although we may need to first complicate things to then simplify them. First, let’s arrange a massive ground plane around the analog circuitry on the PC board. […]
