CAT5270 Dual Digitally Programmable Potentiometers (DPP) with 256 Taps & I2C Compatible Interface Description The CAT5270 is a volatile 256−tap by two channels, digitally programmable potentiometer (DPP) with an I2C compatible interface. Each DPP consists of a linear taper series of resistive elements connected between two externally accessible end points. The tap points between each resistive element are connected to the wiper outputs with CMOS switches. On power up the wiper position goes to .

CAT5271, CAT5273 Dual 256‐position I2C Compatible Digital Potentiometers (POTs) The CAT5271 and CAT5273 are dual 256-position digital programmable linear taper potentiometers ideally suited for replacing mechanical potentiometers and variable resistors. The wiper settings are controlled through an I2C-compatible digital interface. Upon power-up, the wiper assumes a midscale position and may be repositioned anytime after the power is stable. The devices can be programmed to go to a shutdown state.

Dual Digitally Programmable Potentiometers

CAT5270 Dual Digitally Programmable Potentiometers (DPP) with 256 Taps & I2C Compatible Interface Description The CAT5270 is a volatile 256−tap by two channels, digitally programmable potentiometer (DPP) with an I2C compatible interface. Each DPP consists of a linear taper series of resistive elements connected between two externally accessible end points. The tap points between each resistive element are connected to the wiper outputs with CMOS switches. On power up the wiper position goes to mid scale. The CAT5270 can be used as a potentiometer or as a two terminal, variable resistor. It is available in a 14−lead TSSOP package operating over the industrial temperature range (−40°C to 85°C).
