Product Formats Available : Pre-Assembled Module (AS) or Self-Assembly Electronic Kit ( Soldering Required)
Small, battery powered, variable gain mono audio amplifier with volume control using the LM386 IC. The circuit is a little more refined than many we have seen and includes input and output coupling plus power supply decoupling capacitors. Zobel network on output.
Perfect building block in other projects e.g. radio & TV sound system amplifiers, intercoms, line drivers, ultrasonic & servo drivers, voltage converters, small passive speakers, etc.
Ideal for battery operation with it's wide operating supply (4 - 12Vdc) and low quiescent current drain. Volume control pot. LED ON indicator. On/Off switch. Jumper for settable voltage gain of 20 or 200 (26/46dB).
Pre-Amp Kit 3098 is designed specifically for use with this kit where you have an input signal of insufficient amplitude.
