This document describes the features and applications of the CAT5114 32-Tap Digitally Programmable Potentiometer (DPP™) by Catalyst Semiconductor, Inc. The potentiometer has 32-position linear taper, non-volatile EEPROM storage, and ultra-low standby current. It can be incrementally adjusted through a serial interface and can be used as a three-terminal resistive divider or a two-terminal variable resistor.
The CAT5114 is a 32‑tap digitally programmable potentiometer (DPP™) designed as an electronic replacement for mechanical potentiometers and trim pots. It offers non‑volatile EEPROM wiper storage, ultra‑low standby current, and single‑supply operation from 2.5 V to 6.0 V, making it suitable for automated calibration, remote control adjustments, and motor control feedback.
The document details the device’s functional diagram, pin configuration for multiple packages (PDIP, SOIC, TSSOP, MSOP, TDFN), absolute maximum ratings, reliability characteristics, and detailed electrical parameters such as supply current, input leakage, and timing specifications. Ordering information, package options, and revision history are also included.
| Number of Tap Positions | 32 |
|---|---|
| Resistance Options | 10 kΩ, 50 kΩ, 100 kΩ |
| Package Options | PDIP, SOIC, TSSOP, MSOP, 2×3 mm TDFN |
| Maximum Operating Temperature (Industrial) | -40 °C to +85 °C |
It provides 32 tap positions, including the end points.
The CAT5114 is offered in PDIP, SOIC, TSSOP, MSOP, and 2 × 3 mm TDFN packages.
The wiper position is stored in non‑volatile EEPROM and is retained when power is removed, then recalled on power‑up.
