Description and Introduction

High Output Drive, Differential Operational Amplifier with Shutdown The TLV4120IDGNR is a low-power, high-precision voltage reference manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Output Voltage:** 1.2V  
- **Initial Accuracy:** ±0.1% (max)  
- **Temperature Coefficient (TempCo):** 10ppm/°C (typ)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Supply Voltage Range:** 1.8V to 5.5V  
- **Quiescent Current:** 45µA (typ)  
- **Output Current:** ±5mA (sink/source)  
- **Long-Term Stability:** 50ppm/√kHr (typ)  
- **Package:** 8-Pin HVSSOP (DGNR)  

### **Descriptions:**  
The TLV4120IDGNR is a low-dropout (LDO) voltage reference with excellent accuracy and low power consumption, making it suitable for battery-powered and precision applications. It features low noise and high PSRR (Power Supply Rejection Ratio) for stable performance in noisy environments.  

### **Features:**  
- High accuracy (±0.1%)  
- Low quiescent current (45µA)  
- Low dropout voltage (200mV at 5mA)  
- High PSRR (75dB at DC)  
- Low output noise (15µVrms, 10Hz to 100kHz)  
- Stable with capacitive loads up to 10µF  
- AEC-Q100 qualified for automotive applications  

This device is commonly used in data converters, power management, and precision measurement systems.

Application Scenarios & Design Considerations

High Output Drive, Differential Operational Amplifier with Shutdown

Alternative Part Number

  • OPA340NA/3K --: Rail-to-rail CMOS op-amp in SOT-23-5 with similar bandwidth and supply range, widely available and pin-compatible in function.
  • LMV321IDBVR --: Low-voltage rail-to-rail op-amp in SOT-23-5, lower cost general-purpose substitute when bandwidth requirements are relaxed.
  • MCP6001T-I/OT --: Low-power rail-to-rail CMOS op-amp in SOT-23-5 from a different vendor, suitable for similar signal-conditioning applications.
