CAT5110/5118/5119 are 32-tap MiniPot™ digitally programmable potentiometers with ultra-low supply current and single-supply operation. They can be used for LCD screen adjustment, volume control, mechanical potentiometer replacement, etc.
The document details the CAT5110/5118/5119 family of linear-taper digitally programmable potentiometers. These devices consist of a fixed resistor and a wiper contact with 32 tap points, controlled via a 2-wire up/down serial interface. They are available in resistance values of 10kΩ, 50kΩ, and 100kΩ.
| Supply Voltage | 2.7 V to 5.5 V |
|---|---|
| Supply Current (Active) | 0.3 µA |
| Resolution | 32 Taps |
| Operating Temperature Range | -40°C to +85°C |
| Package Types | SC70 and SOT-23 |
The devices are available in 10kΩ, 50kΩ, and 100kΩ configurations.
The position is controlled through a 2-wire up/down serial interface using CS and U/D inputs.
The device features a power-on reset that sets the wiper position to midscale.
