CAT5171/D
CAT5171
256‐position I2C Compatible
Digital Potentiometer (POT)
The CA5171 is a 256-position digital linear taper potentiometer
ideally suited for replacing mechanical potentiometers and variable
resistors.
The wiper settings are controlled through an I2C-compatible digital
interface. Upon power-up, the wiper assumes a midscale position and
may be repositioned anytime after the power is stable. The device can
be programmed to reset the wiper position to midscale or to go to a
shutdown state during operation. An address input pin, AD0, allows
the connection of two devices onto the same I2C bus.
The CAT5171 operates from 2.7 V to 5.5 V, while consuming less
than 2
mA. This low operating current, combined with a small package
footprint, makes the CAT5171 ideal for battery-powered portable
applications.
The CAT5171, designed as a pin for pin replacement for the
AD5245, is offered in the 8-lead SOT23 package and operates over the
40C to +85C industrial temperature range.
