Additional Details

The CAT5110SDI-50-GT3 operates within a specified voltage and temperature range. It is typically available in packages such as SOIC (Small Outline Integrated Circuit). The up/down interface requires only two digital inputs for controlling the wiper position. The device features a power-on reset (POR) circuit to ensure that the wiper starts at a known position after power-up. The CAT5110SDI-50-GT3 is a versatile and reliable DPP for a wide range of applications requiring precise and adjustable resistance settings.
