VMA2016-EVB
http://www.siliconray.com/vma2016-evb.html
This board is a tiny power amplifier board designed with VMA2016. It has one stereo audio input jack, 1 power supply connector and 2 speaker connectors. There's one jumper for enable signal and tow for gain setting of VMA2016. With the outstanding performance of VMA2016 audio amplifier module it can drive 2 8Ohm speaker to unbelievable10W per channel! You just can't believe this small board can singing that loud. The noise is very low and sound quality is excellent (0.07% THD+N). Ultra small size makes it very easy to fit in any speaker boxes to build an active speaker.
Siliconray:NE555 Timer / Oscillator
Siliconray:NE555 Timer / Oscillator
NE555
Brief introduction:
The 555 monolithic timing circuit is a highly stable controller capable of producing accurate time delays or oscillation. In the time delay mode of operation, the time is precisely controlled by one external resistor and capacitor. For a stable operation as an oscillator, the free running frequency and the duty cycle are both accurately controlled with two external resistors and one capacitor. The circuit may be triggered and reset on falling waveforms, and the output structure can source or sink up to 200 mA.
Features:
Max. operating frequency greater than 500 kHz
Turn-off time less than 2 ms
Temperature stability of 0.005% per °C
Timing from microseconds to hours
Adjustable duty cycle
Operates in both astable and monostable modes
High output current
TTL compatible
Applications:
Precision timing
Pulse generation
Sequential timing
Time delay generation
Pulse width modulation
