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 — LIDAR 脉冲飞行时间参考设计

激光雷达 (LIDAR) 系统利用光在物体之间传输所需的时间尝试测量与此目标之间的距离。  TIDA-00663 参考设计展示了如何基于时数转换器 (TDC) 以及相关前端为 LIDAR 设计时间测量后端。  激光雷达脉冲飞行时间参考设计可用于不能通过物理接触来测量与目标之间距离的所有应用。  典型示例包括测量物流中心传送带上是否存在物体,确保移动机械臂周围的安全距离等。
