Inx In518 Ic Pinout Diagram Jun 2026

The two op-amps are independent but share power supply pins (4 and 8). They do not share internal compensation, allowing them to be used for completely different functions (e.g., one as a voltage follower, the other as a comparator).

Designed for low power consumption and high-speed stability to support modern high-resolution displays. Thermal Design: The two op-amps are independent but share power

Signal generators for testing 800x480 and 1024x600 panels often incorporate the IN518. The pinout helps in building a probe adapter. Thermal Design: Signal generators for testing 800x480 and

While official manufacturer datasheets are often proprietary to panel makers, technical repair guides and circuit analysis reveal the following key pin assignments for the IN518: Pin 4 (VCC / Input): Receives the main supply voltage, typically Pin 17 (AVDD): Output for the Analog supply voltage, usually around 15V to 17V Pin 16 (VGL): Output for the gate-off voltage, typically ranging from -5V to -10V Pin 27 (VGH): Output for the gate-on voltage, typically between 20V and 30V Pin 12/13/14 (Enable/Signals):

Usually Pin 4 (in specific 12V configurations), this is the main power input for the IC, typically around 3.3V or 12V depending on the panel design.

If you are probing the IC in a live circuit (using an oscilloscope or multimeter), you should look for these typical values:
