Description and Introduction

LinCMOS(TM) Precision Quad Operational Amplifier The TLC274B is a quad operational amplifier (op-amp) manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**
1. **Supply Voltage Range:** ±1.35V to ±8V (Dual Supply) or 2.7V to 16V (Single Supply)  
2. **Input Offset Voltage:** 950µV (Max) at 25°C  
3. **Input Bias Current:** 1pA (Typ)  
4. **Input Offset Current:** 1pA (Typ)  
5. **Gain Bandwidth Product:** 2.9MHz (Typ)  
6. **Slew Rate:** 3.6V/µs (Typ)  
7. **Common-Mode Rejection Ratio (CMRR):** 85dB (Typ)  
8. **Supply Current per Channel:** 1.4mA (Typ)  
9. **Operating Temperature Range:** -40°C to +125°C  
10. **Package Options:** PDIP, SOIC, TSSOP  

### **Descriptions:**
- The TLC274B is a precision quad operational amplifier with low noise and high input impedance.  
- It is designed for applications requiring low power consumption and rail-to-rail output swing.  
- The device is part of TI's LinCMOS™ technology, offering improved performance over traditional CMOS op-amps.  

### **Features:**
1. **Low Noise:** 19nV/√Hz (Typ) at 1kHz  
2. **Low Power Consumption:** Ideal for battery-operated devices.  
3. **Rail-to-Rail Output Swing:** Maximizes dynamic range.  
4. **High Input Impedance:** 10¹²Ω (Typ)  
5. **ESD Protection:** Up to 2000V (HBM)  
6. **Wide Supply Range:** Supports single and dual supply configurations.  
7. **Stable Operation:** Unity-gain stable with phase margin enhancement.  

This information is strictly based on TI's datasheet for the TLC274B.

Application Scenarios & Design Considerations

LinCMOS(TM) Precision Quad Operational Amplifier

Alternative Part Number

  • LM324N --: Industry-standard quad operational amplifier with similar supply range and pinout, widely available and often used as a direct substitute for TLC274 in non-critical applications.
  • TL074CN --: Low-noise JFET-input quad op-amp with comparable bandwidth and input characteristics, suitable replacement when slightly higher input bias current is acceptable.
  • MC33079PG --: Quad bipolar op-amp with similar supply voltage range and pin configuration, offering a cost-effective alternative for general-purpose signal conditioning.
