The CAT5111 is a 100-position linear taper potentiometer with non-volatile NVRAM wiper storage, buffered wiper, low power CMOS technology, single supply operation, increment up/down serial interface, 10kΩ, 50kΩ, 100kΩ etc. resistance values, available in PDIP, SOIC, TSSOP and MSOP packages. It is suitable for automated product calibration, remote control adjustments, offset, gain and zero control, tamper-proof calibrations, contrast, brightness and volume controls, motor controls and feedback systems, programmable analog functions.
The CAT5111 is a single digitally programmable potentiometer (DPP) designed as an electronic replacement for mechanical potentiometers. It features a 100-position linear taper, non-volatile memory to store the wiper position, and low power CMOS technology suitable for single supply operation between 2.5V and 6.0V.
The device is controlled via three input pins: Chip Select (CS), Up/Down (U/D), and Increment (INC). It offers various resistance values including 10kΩ, 50kΩ, and 100kΩ and is available in PDIP, SOIC, TSSOP, and MSOP packages. Applications include automated calibration, remote control adjustments, and programmable analog functions.
| Supply Voltage Range | 2.5V to 6.0V |
|---|---|
| Number of Taps | 100-position |
| Resistance Values | 10kΩ, 50kΩ, and 100kΩ |
