25W amplifier module LM1875
Full Documentation in pdf format
Kit contains the essential components to build a HiFi amp module using the LM1875 IC. See the documentation for full specifications. Heatsink, speakers and cables are to be supplied by the user.
This kit contains the essential components needed to build a high fidelity amplifier module using the National Semiconductor LM1875 IC. With the addition of a handful of parts and a suitable power supply, this module will deliver 25W RMS into 8 ohms @ 1% THD. PCB dimensions are a tiny 53 x 50mm (2.1” x 2”). Heatsink, power transformer, speaker and cables are not included.(CPS50)

Dual Unregulated Power Supply
Four on-board 100V, 3A diodes plus 2200uF/50V electrolytics to provide an unregulated power supply from a center-tapped transformer. Many power amplifiers require a dual DC power supply for their operation. Usually this consists of some diodes and electrolytic capacitors to convert an AC voltage to a +/- DC voltage. This simple kit does just that, with all the components mounted on a small PCB to avoid the usual spaghetti-wired mass (mess?). The kit is constructed on single-sided printed circuit board. (CPS114)
