Audio Power Amplifier - LM386N-1, Low Voltage
LM386 Low Voltage Audio Power Amplifier The LM386 is a mono low voltage amplifier that can be used in a variety of applications. It can drive loads from 4 Ω to 32 Ω. The gain is internally set to 20 but it can be modified from 20 to 200 by placing a resistor and capacitor between pins 1 and 8. As this is an Op Amp it can be used in different configurations to fit in several applications. The internal gain setting resistor allows the LM386 to be used in a very low part count system. In addition a series resistor can be placed between pins 1 and 5 to modify the gain and frequency response for specific applications. These are found in many small audio amplifiers and even tiny pedal sized guitar amplifiers! There are tons of possibilities for this little Op Amp.

Integrated Circuit - DAB2130, VCO, Sound Semiconductor
The Sound Semiconductor DAB2130 is a pre-soldered DIP converter for the SSI2130. This board features the SSI2130 and two decoupling caps for the V+ and V- inputs. The pinout is labelled on the board and matches the QFN pinout. This adapter features a 32 pin DIP base with a .600 in. width. The pins are standard male headers so 2.54mm female headers are recommended for socketing the board. For the standard QFN version, please see P-Q-SSI2130. The first new VCO IC in decades, and worth the wait! The FatKeys™ SSI2130 Voltage Controlled Oscillator provides beautiful triangle, sawtooth, pulse, and square waveforms with unprecedented temperature stability; and adds an on-chip mixer, low distortion sine wave generator, through-zero FM/PM capability and more in an ultra-compact PCB footprint. The SSI2130 is a new-generation voltage controlled oscillator subsystem for high-performance electronic musical instruments.
