Description and Introduction

60V Fault Protected RS485/RS422 Transceivers The LT1791ACS is a high-speed, low-power operational amplifier manufactured by Linear Technology (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Supply Voltage Range:** ±2.5V to ±6V (5V to 12V single supply)  
- **Input Offset Voltage:** 500µV (max)  
- **Input Bias Current:** 250nA (max)  
- **Gain Bandwidth Product:** 50MHz  
- **Slew Rate:** 25V/µs  
- **Output Current:** ±40mA  
- **Input Common Mode Range:** Includes ground (single-supply operation)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Lead SOIC  

### **Descriptions:**  
- The LT1791ACS is a unity-gain stable, rail-to-rail output operational amplifier optimized for high-speed, low-power applications.  
- It is designed for single or dual-supply operation with a wide input common-mode range, including ground.  
- Suitable for driving capacitive loads and low-impedance loads due to its high output current capability.  

### **Features:**  
- **Low Power Consumption:** 1.5mA supply current per amplifier.  
- **Rail-to-Rail Output Swing:** Maximizes dynamic range in low-voltage applications.  
- **Unity-Gain Stable:** No external compensation required.  
- **High Output Drive:** ±40mA output current.  
- **Wide Supply Range:** Operates from ±2.5V to ±6V (±5V to ±12V total).  
- **ESD Protection:** ±3kV Human Body Model (HBM).

Application Scenarios & Design Considerations

60V Fault Protected RS485/RS422 Transceivers

Alternative Part Number

  • MAX3071EESA+ --: Pin-compatible RS-485/RS-422 transceiver with similar supply voltage and data rate, widely available and often used as a drop-in replacement for the LT1791 family.
  • SN65HVD72DR --: 3.3V RS-485 transceiver with comparable ESD protection and data rate; a common alternative when the LT1791ACS is unavailable.
  • ADM3485EARZ --: Industry-standard RS-485 transceiver with similar electrical characteristics and pinout, suitable for most LT1791ACS applications.
