Description and Introduction

4.5-Bits, 0.003 kSPS ADC, Muxed BCD Output, True Differential Input, 1 Ch. The TLC7135CDW is a 4½-digit analog-to-digital converter (ADC) manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Resolution:** 4½ digits (equivalent to 17,000 counts)  
- **Input Voltage Range:** ±2.000V (full scale)  
- **Conversion Rate:** Up to 3 conversions per second  
- **Supply Voltage:** ±5V (dual supply)  
- **Low Power Consumption:** Typically 1.5mW  
- **Auto-Zero Cycle:** Ensures zero drift  
- **Differential Input:** True differential input with high input impedance  
- **Output Interface:** Multiplexed BCD output with strobes  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** SOIC-28 (DW)  

### **Descriptions and Features:**  
- **High Accuracy:** Provides ±1 count accuracy with auto-zeroing.  
- **Low Noise:** Internal noise reduction for stable readings.  
- **Direct LCD Drive:** Compatible with multiplexed LCD displays.  
- **Overrange and Underrange Indication:** Helps detect out-of-range signals.  
- **Auto-Polarity:** Automatically detects and displays input polarity.  
- **True Differential Input:** Rejects common-mode noise.  

This ADC is commonly used in digital panel meters, process control systems, and other precision measurement applications.
