This operational amplifier test board can be used to test common single-op, dual-op, and quad-op amplifier chips, distinguishing between high-speed and low-speed finished boards. This circuit board can determine whether an IC is suitable for amplification while also assessing the chip's conversion rate. This T2 operational amplifier test board identifies low-speed chips masquerading as high-speed variants. Equipped with LED indicators: For high-speed op-amps, both high-frequency and low-frequency square wave inputs produce normal output, manifested as synchronized illumination of corresponding red and green LEDs-continuous (200kHz) or flashing (10Hz). Test terminals are provided on the board to measure the static current of operational amplifiers under ±5V power supply conditions. The magnitude of static current can reveal certain characteristics of the op-amp and aid in model differentiation. This operational amplifier test board is designed to facilitate the testing of various operational amplifier chips, ensuring accurate performance evaluation and identification of chip characteristics. It provides essential insights into the suitability of ICs for amplification and their conversion rates, making it an invaluable tool for engineers and technicians in the field.
