1W Stereo Amplifier Module DC Volume con

This is a 1 watt stereo amplifier module Kit
using the TDA 7053A from Philips. It uses
a DC voltage to control gain, hence a
single gang pot or switch can be used as a
volume control with minimal tracking error. It
will operate from 4.5 – 18 V DC and requires
no heat-sink for normal use.

1W Stereo Amplifier Module

Uses 2 LM386N-1 for a stereo amplifier. Ideal for walkman and other battery powered items. 4V - 12V DC. Instructions PCB and components supplied.

This is a 1 watt per channel, stereo amplifier module Kit using two LM386N IC’s from National Semiconductor. It is basically two of our CPS17’s on a single PC board, with a dual gang pot. It will operate best from 6-12V DC and will work well from a battery since the quiescent current drain is only 10 mA. It requires no heat sinks for normal use. The input and output are both ground referenced. Maximum output will be obtained with a 12V power supply and 8 ohm speaker, however it is particularly suitable for driving headphones from a supply as low as 4V. Speakers are not supplied. They should be rated at 3W or over. PCB size 63mm x 40mm (2.5" x 1.5"). (CPS115)

2W amplifier module LM380

This is a very simple amplifier built around the LM380 IC. It can deliver up to 2W into an 8 ohm speaker depending on the supply voltage. Instead of using a heatsink or heat fins the heat produced is dissipated through the center pins of the IC into the copper overlay left on the PCB. If you do require a sustained output of more than ½ watt, you will need to add a heatsink (not included). The IC solders directly to the PCB.
PCB size: 1.75in x 1.75in (45mm x 45mm)

Power output:
> 2 Watt max. (4-8 ohms, 20V)
> 1 Watt max. (4-8 ohms, 12V)
> 0.5 Watt RMS continuous

Introduction to Class AB Amplifiers

Using amplifier modules is modern, quick and easy but it teaches nothing about how they work. Here is a Class AB amplifier made from individual components which will deliver several watts of power into an ordinary 8 ohm speaker. Gives hands-on learning about cross-over distortion, bootstrapping, complementary pairs, and push-pull. Detailed explanations given. Terminal strips are used for inputs and outputs. Use two 9 volt batteries. PCB Size: 2in (L) X 1.5in (W) (CPS48)
