Description and Introduction

PROXIMITY DETECTORS The TDA0161DP is a proximity detector IC manufactured by STMicroelectronics. Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Supply Voltage (VCC):** 3.5V to 12V  
- **Operating Current:** 1.5mA (typical)  
- **Output Current (Sink):** 10mA (max)  
- **Frequency Range:** 100kHz to 1MHz (adjustable via external LC circuit)  
- **Package:** DIP-8 (Plastic Dual In-line Package)  

### **Description:**  
The TDA0161DP is a monolithic integrated circuit designed for proximity detection using inductive sensing. It operates by detecting changes in the oscillation amplitude of an LC tank circuit caused by the presence of a metallic object.  

### **Features:**  
- **Inductive Proximity Detection:** Detects metal objects without physical contact.  
- **Adjustable Sensitivity:** Sensitivity can be tuned using an external LC resonant circuit.  
- **Low Power Consumption:** Suitable for battery-operated applications.  
- **Built-in Oscillator:** Requires minimal external components.  
- **Output Stage:** Open-collector output for easy interfacing with microcontrollers or relays.  
- **Wide Supply Voltage Range:** Supports operation from 3.5V to 12V.  

This IC is commonly used in applications such as security systems, industrial automation, and object detection.
