The goal of audio amplifiers is to reproduce input audio signals at sound-producing output elements, with desired volume and power levels—faithfully, efficiently, and at low distortion. Audio frequencies range from about 20 Hz to 20 kHz, so the amplifier must have good frequency response over ...
This switch is used to enable or disable the 12 volt trigger sensing circuitry on the amplifier. If the switch is set to the ON position, the power amplifier will remain in standby mode until it detects a 12 volt signal at the 12V Trigger Input on the back panel. When the 12 volt sig...
Please apply negative feedback to the operational amplifier so that the gain is flat up to the operating band. Also, be careful of oscillations at frequencies close to unity gain. There is an explanation in the op amp e-learning 2.3. Oscillation. Oscill...
A voltage follower (also called a unity-gain amplifier, a buffer amplifier, and an isolation amplifier) is a op-amp circuit which has a voltage gain of 1. This means that the op amp does not provide any amplification to the signal. The reason it is called a voltage follower is because...
Learn what is a signal amplifier, how does it work, its applications, benefits, and how they are used in the context of a data acquisition (DAQ) system.
Having the ability to feed controls to these motors from a central amplifier and system means they can be custom-designed with digital programming or connected to tie into existing analog data streams. What is the point of a piezo motor over the available alternatives? There are numerous reasons...

Internet radio is on board of course, along with Bluetooth, streaming via the most popular music services and a USB-C port for charging your mobile. There are even physical connections for plugging in an MP3 player and wired headphones. And while the sound quality is a bit of a departure ...
What is an op-amp? An operational amplifier (op-amp) is an integrated circuit (IC) that amplifies the difference in voltage between two inputs. It is so named because it was developed for perform arithmetic operations. Amplifiers, buffers, comparators, filters, etc. can be i...
An electronic circuit that increases the amplitude of its input signal and outputs the result. The most familiar type is the audio amplifier, as found in domestic hi fi or telephones, but amplifiers are to be found in every sort of device, including sili
