Eden Microphone Preamplifier | expataudio This is the Eden Microphone Preamplifier from Expat Audio. It comes are a completed module that only needs to be hooked up. In fact, all it needs is power, input, output and a gain setting resistor. It's assembled and tested here in Texas, USA. Performance It has flat THD+N at 30dB of gain as low as 0.003%, all the way to 30kHz (higher I believe - but the audio test kit isn't quite up to it).

Deciphering Electrical Characteristics in an Op Amp Datasheet The Operational Amplifier (Op Amp) is often the key analog gain block in acquiring and scaling real world signals in any data acquisition system. To predict system accuracy when using op amps it is important to understand the op amp data sheet and how individual specifications affect both the DC and AC transfer accuracy through the op amp.

SCIENCE HOBBYIST: how transistor works, an alternate viewpoint Voltage-driven charge-flows First of all, you must abandon the idea that current travels in transistors or flows inside of wires.
Before we describe anything technical, let's see one in action. An op-amp can be connected to a single voltage rail (called UNIPOLAR SUPPLY - 0v to Vcc) or a dual voltage rail (called BIPOLAR SUPPLY +/-Vcc). The OP-AMP
