Product Description


The LDA355 (instead of TCA355) is an ASIC developed for inductive proximity switch applications. It can be used in a wide range of proximity sensors or proximity control systems. It can also be used to make a variety of inductive instrumentation such as inductive tachometers. LDA355 has the characteristics of high integration, wide working voltage, large output current, adjustable control distance, few peripheral circuits, convenient application and stable and reliable operation. Compared with the inductive proximity switch scheme composed of general discrete components, the LDA355 integrated chip solution has better consistency and stability, so it is especially suitable for high reliability and high reliability.
