CAT5172TBI-50GT3 Цифровые потенциометры от ON Semiconductor

256-Position SPI Compatible Digital Potentiometer
The CAT5172 is a 256−position digitally programmable linear taper potentiometer ideally suited for replacing mechanical potentiometers and variable resistors. Like mechanical potentiometers, the CAT5172 has a resistive element, which can span VCC to Ground or float anywhere between the power supply rails.Wiper settings are controlled through an SPI−compatible digital interface. Upon power−up, the wiper assumes a mid−span position and may be repositioned anytime after the power is stable.
