The CAT5172TBI-50GT3 from ON Semiconductor is a 256-position digital potentiometer designed to replace mechanical potentiometers and variable resistors. It offers a linear taper with an end-to-end resistance of 50kΩ and a typical tolerance of ±20%.
This device utilizes an SPI-compatible digital interface for wiper control, with the wiper assuming a mid-span position upon power-up. It operates from a single supply voltage ranging from 2.7V to 5.5V and consumes very low power, less than 2 µA maximum.
The CAT5172TBI-50GT3 is housed in a compact SOT-23-8 package, making it suitable for space-constrained applications. Its wide operating temperature range of -40°C to +85°C and low temperature coefficient of ±100ppm/°C ensure reliable performance in various environments.
Typical applications include potentiometer replacement, adjustment of transducer outputs (pressure, temperature, position, chemical, optical sensors), RF amplifier biasing, and gain control or offset adjustments.
The operating voltage range is 2.7V to 5.5V.
The CAT5172TBI-50GT3 is supplied in a SOT-23-8 surface mount package.
The operating temperature range is -40°C to 85°C.
The RoHS status is Compliant.
The end-to-end resistance is 50kΩ.
The device has 256 taps.
It uses an SPI interface.
