DESCRIPTION:
2 sine wave and 2 square wave output
AD9850 Frequency: 0-40MHz
After the 20-30MHz frequency harmonics increases, the waveform will become unclean.
Square Wave: 0-1MHz
Low-pass filter with 70MHz, so the waveform better than SN
Parallel and serial data input can be selecte..
DESCRIPTION:
1,An onboard chip NE555
2, a single-channel signal output, the output is approximately fifty percent duty cycle square wave
3, onboard adjustable resistance, adjust the output frequency can be controlled resistance
4, on-board power indicator
5, the working voltage: 5 ~ 1..

UM3561 is a low-cost, low-power CMOS LSI designed for use in alarm and toy applications. Since the integrated circuit includes oscillator and selector circuits, a compact sound module can be constructed with only a few additional components. The M3561 contains a programmed mask ROM to simulate siren..
