Overview

CAT5121 リニアテーパ・デジタル POT は、機械式ポテンショメータや可変抵抗器と同じ機能を果たします。固定抵抗器とワイパで構成されています。ワイパはタップ・ポイントで固定抵抗器に接触します。どのポイントで接触するかは 2 線アップ/ダウン・シリアル・インタフェースを介してデジタル的に制御されます。CAT5121 は可変抵抗器として構成されています。機能については、ピン構成を参照してください。 10 kΩ、50 kΩ、および 100 kΩ の 3 つの抵抗値があります。

  • 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.)
