Générateur de signal carré NE555 Ajustable

• Chip:NE555
• Input Voltage:5V-15VDC.
• Input current: ≥ 100MA
• Maximum output current: ≥15MA (5V power supply, V-PP greater than 50%), ≥ 35MA (12V power supply, V-PP greater than 50%)
• Output Amplitude: 4.2V V-PP to 11.4V V-PP
• Output with LED indication
• Output frequency range grade optional:

                                            Low-frequency stall: 1Hz-50Hz
                                            IF stall: 50Hz-1kHz
                                            In the high-frequency stall: 1KHz-10kHz
                                            High-frequency stall: 10kHz-200kHz

•     Output frequency is adjustable :

                                            the Cycle T = 0.7*(Ra + 2*Rb)*C
                                            Ra, Rb:0-10K adjustable
                                            LF gear C = 0.001UF
                                            IF file C = 0.1UF
                                            In the high-frequency file C = 1UF
                                            High-frequency gear C = 100UF      

NOTE:Output duty cycle can fine-tune, the duty cycle and frequency is not adjustable separately adjust the duty cycle will change the frequency.
