Description: - Operational amplifier tester, operational amplifier quality testing tool, which is specially designed for SOIC packaging, suitable for general single and dual operational amplifiers, with sound and light prompts for detection/failure, accurate and efficient. The principle is that after precise voltage division and buffering, multiple ADC scanning ports automatically calculate the fluctuation range and stability. The test can be completed in 1-3 seconds, and both dual 5V and single 5V power can be used to power the tested operational amplifier. A manual switch is used to select suitable for classic operational amplifiers (such as OP07) and new operational amplifiers (low-voltage single power rail to rail) - The instrument can be powered by ordinary wires or a transformer with a DC plug, with a supply voltage of 5.5V-12.5V. Instructions: - Insert the power supply into the power socket, and the instrument will experience a brief beep and flashing light. - After about 3 seconds, it will enter the working state, and then place the operational amplifier into the test stand according to its schematic diagram. If it is a SMD component, you can use tweezers to assist in placing it. After placing it, press the test button, and the instrument will start working. - If the tested operational amplifier passes the test, the instrument emits a short beep of "di". If it fails, it emits three short beeps of "di di di", and the LED indicator on the panel displays the situation of pass (PASS) or fail (DAMAGE). Package Included: 1 x Operational Amplifier Tester
