Key specifications Main chip: N5555 Input power: DC 515 V Output amplitude: 4.2 VPP at 5 V input up to 11.4 VPP at 12 V input (output amplitude varies with input) Output frequency ranges: four selectable bands 1 Hz 50 Hz 50 Hz 1 kHz 1 kHz 10 kHz 10 kHz 200 kHz Output current capability: approximately 15 mA at 5 V supply; approximately 35 mA at 12 V supply Duty cycle: adjustable; note that duty cycle and frequency are not independently adjustable; changing the duty cycle will affect the frequency Performance and compatibility Designed to operate from a DC supply within 515 V Amplitude scales with input voltage, enabling higher peaktopeak output when fed from a higher supply Four distinct frequency bands cover common lab and test needs from slow waveforms to relatively frequency signals Duty cycle can be finely tuned, with the caveat that adjusting it will influence the output frequency Use scenarios Lab signal generation: provide a reliable test signal for smallsignal circuits, microcontroller inputs, or sensor simulations using either 5 V or 12 V supplies Educational demonstrations: illustrate how duty cycle and frequency interact, and show how amplitude changes with input voltage in a practical waveform source Electronics testing: simulate realworld signals for component testing, calibration, or debugging within the specified amplitude and frequency ranges Notes Output amplitude is specified as 4.2 VPP to 11.4 VPP, and the exact value depends on the input voltage Duty cycle and frequency are not independently adjustable; adjustments to the duty cycle will affect frequency
