We published a design for a stereo microphone preamplifier with balanced inputs and a phantom power supply. The heart of this circuit was a special Analog Devices IC, the SSM2017. Unfortunately, this ...
The circuit is aimed to build a computer sound card with input line in order to use a two mono stereo microphone. TLC272 – a precision dual operational amplifier with low offset voltage drift, low ...
Conventional wisdom has it that the solid state era in electronics began in 1948 with the invention of the transistor, or if you wish to split hairs, with the 1930s invention by the Russian [Oleg ...
