Description and Introduction

Advanced LinCMOS TM HIGH-SPEED 8-BIT ANALOG-TO-DIGITAL CONVERTERS USING MODIFIED FLASH TECHNIQUES The TLC0820ACDBRG4 is a dual operational amplifier manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage Range:** ±2.25V to ±8V (Dual Supply) or 4.5V to 16V (Single Supply)  
- **Input Offset Voltage:** 1.5mV (Typical), 3mV (Maximum)  
- **Input Bias Current:** 1pA (Typical)  
- **Gain Bandwidth Product:** 3MHz (Typical)  
- **Slew Rate:** 2.4V/µs (Typical)  
- **Common-Mode Rejection Ratio (CMRR):** 80dB (Typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin SOIC (DBR)  

### **Descriptions:**
- The TLC0820ACDBRG4 is a dual, low-power, high-speed JFET-input operational amplifier.  
- It is designed for precision applications requiring low noise and high input impedance.  
- Suitable for battery-powered and portable devices due to its low power consumption.  

### **Features:**
- **Low Power Consumption:** 1.4mA per amplifier (Typical)  
- **High Input Impedance:** JFET input stage (10^12Ω typical)  
- **Wide Supply Voltage Range:** Supports single and dual supplies.  
- **Low Noise:** 18nV/√Hz (Typical at 1kHz)  
- **Rail-to-Rail Output Swing:** Ensures maximum dynamic range.  
- **ESD Protection:** Up to 2000V (HBM)  

This amplifier is commonly used in audio processing, signal conditioning, and active filtering applications.

Application Scenarios & Design Considerations

Advanced LinCMOS TM HIGH-SPEED 8-BIT ANALOG-TO-DIGITAL CONVERTERS USING MODIFIED FLASH TECHNIQUES

Alternative Part Number

  • ADC0820CCN --: Pin-compatible 8-bit CMOS ADC from the same family lineage with similar conversion architecture, widely available as a direct functional substitute.
  • ADC0804LCN --: Classic 8-bit successive-approximation ADC with comparable resolution and interface, commonly used as a drop-in alternative in similar designs.
  • MCP3208-CI/P --: 12-bit SPI ADC offering higher resolution and similar sampling capability, suitable as an upgraded replacement when board layout allows interface changes.
  • ADC0820BCN --: Same ADC0820 series with tighter accuracy grade, directly interchangeable in most 8-bit sampling applications.
  • MAX150BCP --: Alternative 8-bit CMOS ADC with similar sampling architecture and parallel interface, suitable for designs needing a second-source option.
