Description and Introduction

1.8V, INPUT/OUPUT RAIL TO RAIL LOW POWER OP-AMPS The TS1871ID is a low-power operational amplifier (op-amp) manufactured by STMicroelectronics. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage Range:** 2.7V to 5.5V  
- **Input Offset Voltage:** 3 mV (max)  
- **Input Bias Current:** 1 pA (typ)  
- **Gain Bandwidth Product (GBW):** 1.4 MHz  
- **Slew Rate:** 0.6 V/µs  
- **Quiescent Current:** 450 µA (per amplifier)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SO-8  

### **Description:**
The TS1871ID is a single-channel CMOS operational amplifier designed for low-power applications. It offers rail-to-rail input and output operation, making it suitable for battery-powered devices and precision signal conditioning.

### **Features:**
- **Low Power Consumption:** Optimized for battery-operated systems.  
- **Rail-to-Rail Input/Output:** Ensures maximum dynamic range.  
- **Low Input Bias Current:** Ideal for high-impedance sensor interfaces.  
- **Stable with Capacitive Loads:** Up to 100 pF.  
- **ESD Protection:** Up to 2 kV (HBM).  

This op-amp is commonly used in portable devices, sensor interfaces, and low-voltage signal processing applications.

Application Scenarios & Design Considerations

1.8V, INPUT/OUPUT RAIL TO RAIL LOW POWER OP-AMPS

Alternative Part Number

  • LMV321IDBVR --: Low-voltage rail-to-rail op-amp with similar 1.8V-5.5V supply range and SOT-23-5 package, a common drop-in alternative to the TS1871.
  • OPA340NA/3K --: Rail-to-rail input/output single op-amp with comparable bandwidth and low supply voltage operation, suitable replacement in SOT-23-5.
  • MCP6001T-I/OT --: Low-power rail-to-rail single op-amp in SOT-23-5 with 1.8V-6V supply, functionally similar to the TS1871 for general signal conditioning.
