This circuit is from a 1975 Miniwatts magazine, therefore using Philips components from that time, now difficult to find. The circuit directly controls a heating element via a Triac.
The first circuit we present is ideal for matching the low impedance of transducers, such as...
Found in Linear Technology documentation, this amplifier requires a symmetrical power source and...
