Digital Potentiometer 100kOhm 256POS Linear 8-Pin SOT-23 T/R

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. The CAT5172 operates from 2.7 V to 5.5 V while consuming less than 2 A. This low operating current combined with a small package footprint makes the CAT5172 ideal for battery powered portable appliance.
