CAT5172 Datasheet 256-position Spi Compatible Digital Potentiometer

Manufacturer: onsemi

Overview: CAT5172 256‐position SPI patible Digital Potentiometer (POT) The CAT5172 is a 256-position digital 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-patible digital interface. Upon power-up, the wiper assumes a mid-span position and may be repositioned anytime after the power is stable. The CAT5172 operates from 2.7 V to 5.5 V, while consuming less than 2 mA. This low operating current, bined with a small package footprint, make the CAT5172 ideal for battery-powered portable appliance.
