- Wide supply voltage range (±1.35V to ±18V)  
- High CMRR (110dB min at G = 100)  
- Low input offset voltage (50µV max)  
- Low input bias current (5nA max)  
- Adjustable gain (1 to 10,000) via external resistor  
- High accuracy and stability  
- Available in PDIP-8 package  

This information is strictly based on the manufacturer's datasheet and technical specifications.

Application Scenarios & Design Considerations

Precision, Low Power Instrumentation Amplifier 8-PDIP -40 to 85

Alternative Part Number

  • AD8221ARZ --: Pin-compatible instrumentation amplifier with similar gain bandwidth and low offset, direct functional replacement in most INA118 circuits.
  • LT1167CS8 --: Low-noise instrumentation amplifier with comparable gain range and supply voltage, suitable drop-in substitute for precision sensor front ends.
  • INA128PA --: Same instrumentation amplifier family architecture with similar gain equation and package, widely available and cost-effective alternative.
  • AD620ANZ --: Industry-standard precision instrumentation amplifier with similar gain range and pinout, widely used as a direct substitute for the INA118 in low-noise instrumentation designs.
  • LT1167CN8 --: Low-noise instrumentation amplifier with similar gain-setting architecture and DIP-8 package, suitable as a functional replacement where supply and gain requirements match.
