Dual-channel digital potentiometers with 256 resistor taps for fine resolution adjustment and an I2C-compatible interface for maximum interoperability.
New 256-Tap Digital Potentiometers for Control of Up to 16 Devices on One Bus

New devices offer volatile wiper register for applications using MCU with on-chip memory for wiper recall, or systems not requiring memory

PHOENIX, Ariz. – Oct. 13, 2009 – ON Semiconductor (Nasdaq: ONNN) a leading global supplier of high performance, energy efficient silicon solutions, today announced the availability of two new Digitally Programmable Potentiometer (DPP™) ICs suitable for high accuracy and stability for variable resistance adjustment applications in a wide range of industrial and consumer products. The CAT5270 and CAT5271 are dual-channel digital potentiometers with 256 resistor taps for fine resolution adjustment and an I2C-compatible interface for maximum interoperability. The new ON Semiconductor DPPs feature a volatile wiper register making them ideal for applications using a microcontroller (MCU) with on-chip memory for wiper recall, or for systems that do not require memory.
