Description and Introduction

Precision, Low Drift, CMOS Instrumentation Amplifier 8-VSSOP -40 to 85 The INA326EA/2K5G4 is a precision instrumentation amplifier manufactured by Texas Instruments (TI)/Burr-Brown (BB).  

### **Specifications:**  
- **Supply Voltage Range:** ±1.35V to ±18V (Dual Supply), 2.7V to 36V (Single Supply)  
- **Low Quiescent Current:** 700µA (Typical)  
- **Input Offset Voltage:** 150µV (Maximum)  
- **Input Bias Current:** 10nA (Maximum)  
- **CMRR (Common-Mode Rejection Ratio):** 100dB (Minimum)  
- **Gain Bandwidth Product:** 1MHz (Typical)  
- **Gain Range:** 1 to 1000 (Set with External Resistor)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-8  

### **Descriptions:**  
The INA326 is a low-power, precision instrumentation amplifier with rail-to-rail output swing. It is designed for applications requiring high accuracy and low power consumption, such as sensor signal conditioning, medical instrumentation, and industrial process control.  

### **Features:**  
- **Rail-to-Rail Output Swing**  
- **Low Power Consumption**  
- **Wide Supply Range**  
- **High CMRR and PSRR (Power Supply Rejection Ratio)**  
- **Single External Resistor Sets Gain**  
- **Stable with Capacitive Loads Up to 1000pF**  
- **Small SOT-23 Package for Space-Constrained Applications**  

This amplifier is ideal for battery-powered and portable devices due to its low power consumption and wide operating voltage range.

Application Scenarios & Design Considerations

Precision, Low Drift, CMOS Instrumentation Amplifier 8-VSSOP -40 to 85

Alternative Part Number

  • AD8226ARZ --: Instrumentation amplifier with similar low-offset, rail-to-rail output performance and wide supply range, suitable as a functional replacement in most signal-conditioning circuits.
  • INA333AIDGKT --: Low-power zero-drift instrumentation amplifier from a different TI series, offering comparable gain accuracy and low offset for precision sensor interfaces.
  • LT1167ACS8 --: Precision instrumentation amplifier with low gain error and high CMRR, usable as an alternative when the INA326 is unavailable, though pinout and package differ.
