An experienced circuit-design EE once clarified his view of the hierarchy of IC-vendor design support: High-performance, feature-rich ICs were good, application circuits were better, but complete ...

Isolation is needed now more than ever with applications like LED lighting, brushless motors, power monitoring, and many others that are a combination of direct offline power electronics with isolated ...

In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...

Recently, [Edward Schmitz] wrote in to let us know about his Hackaday.io project: SigCore UC: An Open-Source Universal I/O Controller With Relays, Analog I/O, and Modbus for the Raspberry Pi. In the ...

In previous installments of the AudioFile, we’ve talked about basic PCM audio, which encodes audio into a series of numbers that a computer can play or manipulate. We’ve also discussed the process of ...
