Description and Introduction

4.5-Bits, 0.003 kSPS ADC, Muxed BCD Output, True Differential Input, 1 Ch. The TLC7135CN is a 4½-digit analog-to-digital converter (ADC) manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Resolution:** 4½ digits (equivalent to 17,000 counts).  
- **Input Voltage Range:** ±2V (full-scale range).  
- **Conversion Rate:** Up to 3 conversions per second.  
- **Supply Voltage:** ±5V (dual supply).  
- **Power Consumption:** Typically 8mW.  
- **Reference Voltage:** External (typically 1V for full-scale input).  
- **Input Impedance:** >10¹² Ω.  
- **Operating Temperature Range:** 0°C to +70°C (commercial grade).  
- **Package:** 28-pin PDIP (Plastic Dual In-line Package).  

### **Descriptions:**  
- The TLC7135CN is a precision ADC with auto-zeroing and differential input capability.  
- It is designed for high-accuracy digital panel meters and measurement applications.  
- Includes multiplexed BCD outputs for interfacing with microcontrollers or displays.  
- Features auto-polarity and auto-zeroing for improved accuracy.  

### **Features:**  
- **True Differential Input:** Measures the difference between two input voltages.  
- **Auto-Zero Function:** Eliminates offset errors.  
- **Auto-Polarity Detection:** Automatically detects positive or negative input voltages.  
- **Low Noise:** Ensures stable and accurate readings.  
- **Multiplexed BCD Output:** Simplifies interfacing with digital displays or processors.  
- **Overrange and Underrange Indication:** Flags when input exceeds the measurement range.  

This information is based solely on TI's documented specifications for the TLC7135CN.
