Overview
The INA116UAG4 is a monolithic FET-input instrumentation amplifier from Texas Instruments, featuring Difet inputs for ultra-low input bias current. It operates within a supply voltage range of 5V to 36V and supports a gain range of 1 to 10,000 V/V. Key electrical specifications include a minimum common-mode rejection ratio (CMRR) of 86 dB, a typical bandwidth of 0.8 MHz at minimum gain, and a maximum gain error of 0.7%. The device is housed in a 16-pin SOIC package and is rated for operation between -40°C and +85°C.
Feature Summary
- Ultra-low input bias current achieved through specialized Difet input technology
- Wide single-supply operating voltage range supporting diverse power environments
- High precision performance with low gain error and high common-mode rejection
Applications
- Precision sensor signal conditioning
- Medical instrumentation front-ends
- Industrial process control systems
Procurement Notes
Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as per Texas Instruments documentation. Confirm the 16-pin SOIC package type matches your PCB footprint requirements. Ensure the ordering quantity aligns with manufacturer reel specifications if applicable. Cross-reference the datasheet revision date to ensure compatibility with current design standards.
Selection Notes
Select this component when ultra-low input bias current is critical for maintaining accuracy with high-impedance sources. The wide supply voltage range offers flexibility compared to lower-voltage alternatives. Consider the 16-pin package size relative to board space constraints. Evaluate the 0.8 MHz bandwidth against your signal frequency requirements to ensure sufficient speed without unnecessary power consumption.
Part Context
The INA116 belongs to Texas Instruments' family of precision instrumentation amplifiers designed for high-accuracy applications. It complements other models like the INA118 by offering FET-input characteristics suitable for different impedance levels. This series is widely used in measurement systems requiring stable gain and minimal drift over temperature variations.
Replacement Considerations
The INA116UA is a compatible variant within the same product line. Verify pinout and electrical specifications match before substitution. Other Difet-input amplifiers may serve as alternatives if package or parameter differences are acceptable.
