TDA0161 Metal Proximity Detector IC

Product Description

Introduction

LDA0161ˆanalog TDA0161The monolithic integrated circuits are designed for metallic body detection by detecting the vari ations in high frequency Eddy current losses. With an external tuned circuit they act as oscillators. Output signal level is altered by an approaching metallic object. Output signal is determined by supply current changes. Independentof supply voltage, this cur rent is high or low according to the presence or the absence of a close metallic object

Feature

• SUPPLY VOLTAGE : + 4 to + 35 V
• Current consumption: <0.8 mA
• Output current: > 10 mA
• Working temperature: -30ƒ ~ 70ƒ
• Low external components and high sensitivity
