Digital Potentiometers (POTs) | CAT5122

Digital Potentiometer (POT), 16-Tap, with 2-Wire Interface

Obsolete

Datasheet

Products

Overview

CAT5122 linear-taper digital POT performs the same function as a mechanical potentiometer or a variable resistor. This device consists of a fixed resistor and a wiper contact with 32-tap points that are digitally controlled through a 2-wire up/down serial interface.

The CAT5122 is configured as a variable resistor. See Pin Configurations for part functionality.
Three resistance values are available: 10 kΩ , 50 kΩ and 100 kΩ.

  • LCD screen adjustment
  • Volume control
  • Mechanical potentiometer replacement
  • Gain adjustment
  • Line impedance matching

  • Industrial Equipment

  • 0.3 µA Ultra-low supply current
  • Single-supply operation: 2.7 V to 5.5 V
  • Glitchless switching between resistor taps
  • Power-on reset to midscale
  • 2-Wire up/down serial interface
  • Resistance values: 10 kΩ, 50 kΩ and 100 kΩ

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
