The TPL0202 has two linear-taper digital potentiometers (DPOTs) with 256 wiper positions. Each potentiometer can be used as a three-terminal potentiometer or as a two-terminal rheostat. The TPL0202-10 has an end-to-end resistance of 10 kΩ.

This DPOT can be used as a mechanical potentiometer replacement, allowing the user (or software) to digitally control and adjust resistance.

The TPL0202 has non-volatile memory (EEPROM) which can be used to store the wiper position for automatic recall upon power-up. The internal registers of the TPL0202 can be accessed using a SPI-compatible digital interface.

TIDA-00663 — 光達脈衝飛時測距參考設計

光線偵測與測距(光達)系統利用光在目標物間來回飛行所花費的時間,測量與此目標的距離。  TIDA-00663 參考設計展示如何根據時間轉數位轉換器 (TDC) 和相關前端,設計 LIDAR 的時間測量後端。  LIDAR 脈衝飛時測距參考設計適用於無法透過物理接觸來測量目標距離的各類應用。  典型的範例包括測量物流中心傳送帶上的物體,確保移動機器手臂周圍的安全距離等。
