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

20 second voice recorder/playback module (A93010/A96010)

PLEASE NOTE: This module, part# A96010, could actually be either an A96010 or an A93010 depending on what is in stock at the time. Both are virtually identical and operate the same, but downloadable datasheets are available for each for comparison if necessary. The small size is because the IC is in Chip-on-board form. One button is pushed down to record the message through the on-board electret microphone; A LED turns on during this time. The other button just has to be momentarily pressed to replay the message. A second momentary press during playback will stop the playback. Sampling rate is 4K. All you have to add is the speaker (not included) and 5V DC power (not included). We also have an A96010-kit which in addition to the A96010 also includes a speaker and two cable connectors to connect the unit to a power supply (not included) and the speaker. The record/play time is determined by the 52K resistor. If you change it to 89K you will get 30 seconds but at a reduced sampling rate. Operating current 25mA. Standby current 10 uA. Size: 34 x 23 x 11 mm. The module comes supplied as you see it in the photo.

OPTIONAL ITEMS (Not included):
2 x (BB089) connector cable to connect the voice recorder to a speaker and power source.
1 x (PB244) Speaker
1 x Battery holder that can hold either 4 x AAA or 4 x AA or 4 x C or 4 x D cells. See our battery holders.

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)
