The CAT5137SDI-00GT3 from ON Semiconductor is a digital potentiometer designed to function like a mechanical potentiometer. It offers 128 discrete tap points across its 100k Ohm resistance range, controlled via an I2C serial bus.
This device operates with a digital supply voltage between 2.7V and 5.5V and features a linear taper. The wiper position is set to mid-scale upon power-up. It is housed in a compact 6-pin SC-70 package, suitable for surface mount applications.
Key electrical specifications include a ±20% tolerance and a typical temperature coefficient of ±300ppm/°C. The operating temperature range is industrial, from -40°C to +85°C. The CAT5137SDI-00GT3 is configured as a rheostat and uses volatile memory.
Typical applications for this digital potentiometer include LCD screen adjustment, volume control, gain adjustment, and as a direct replacement for mechanical potentiometers.
The end-to-end resistance is 100k Ohm.
It has 128 taps.
It uses an I2C interface.
The operating voltage range is 2.7V to 5.5V.
The operating temperature range is -40°C to +85°C.
It is supplied in a 6-TSSOP, SC-88, SOT-363 package, specifically the SC-70-6 supplier device package.
