The CAT5138SDI-10GT3 is a single linear digital potentiometer from ON Semiconductor, offering 128 taps and an I2C interface for digital control. It functions similarly to mechanical potentiometers, with tap points connected to the wiper via CMOS switches controlled by a 7-bit Wiper Control Register.
This device provides an end-to-end resistance of 10 kOhm with a tolerance of ±20% and a temperature coefficient of ±300ppm/°C. It operates within a digital supply voltage range of 2.7V to 5.5V and an industrial temperature range of -40°C to +85°C. The wiper is set to mid-scale upon power-up.
Packaged in a 6-pin SC-70 package, the CAT5138SDI-10GT3 is suitable for surface mount applications. Its configuration as a rheostat makes it ideal for applications such as LCD screen adjustment, volume control, gain adjustment, and as a direct replacement for mechanical potentiometers.
