ON Semiconductor Launches CAT5171 and CAT5172, New High-Resolution Devices Incorporating I2C and Serial Peripheral Interface (SPI) 256-tap

The CAT5171 and CAT5172 are family of Digitally Programmable Potentiometer (DPP™) ICs with new high-resolution devices incorporating I2C and Serial Peripheral Interface (SPI) Bus connectivity. The new DPPs offer a low-noise, reliable and space-saving alternative to mechanical potentiometers in applications ranging from instrumentation and industrial automation to portable battery-powered equipment. The CAT5171 and CAT5172 are single-channel, digitally programmable linear taper potentiometers featuring 256-position resolution. Digital control of wiper settings is made via I2C and SPI interfaces respectively and both devices are available with end-to-end resistance options of 50 kiloohms, (kO) and 100 kO. The CAT5171 and CAT5172 are insensitive to mechanical vibrations, shock, oxidation, and dust and dirt unlike their mechanical counterparts. Each device also has a low temperature coefficient of 100 part per million per degrees Celsius (ppm/ºC)…
