- Maximum output current: 15mA with a 5V power supply (V-PP > 50%); 35mA with a 12V power supply (V-PP > 50%). The output features an LED indicator: LED is on at low level, off at high level, and flashes at low frequency. - Output amplitude ranges from 4.2V V-PP (with 5V input) to 11.4V V-PP (with 12V input). Note that output amplitude varies with input voltage. - Power supply specifications: - 5V: output current approximately 15mA - 12V: output current approximately 35mA - Main chip: N5555. Compatible input voltage range is DC 5-15V. Output frequency options include four ranges: 1Hz-50Hz, 50Hz-1KHz, 1KHz-10KHz, and 10KHz-200KHz. Applications: 1. Ideal for signal generation in electronic projects, providing adjustable frequency and amplitude for testing circuits. 2. Suitable for LED control systems, allowing users to create visual effects based on frequency modulation. 3. Perfect for audio applications, where precise frequency output is needed for sound synthesis or modulation. This product combines versatility, performance, and reliability, making it a valuable addition to any electronics toolkit.
