Overview
The INA114AP is a precision instrumentation amplifier manufactured by Texas Instruments, housed in an 8-pin PDIP package. It operates on dual power supplies ranging from ±2.25V to ±18V (total 4.5V to 30V) with a typical supply current of 2.2mA. Key electrical specifications include a minimum Common-Mode Rejection Ratio (CMRR) of 110dB, an input offset voltage of 125µV, and an input bias current of 500pA. The device features a gain bandwidth product of 1MHz and a slew rate of 60mV/µs. It supports a wide operating temperature range from -40°C to +85°C.
Feature Summary
- High common-mode rejection ratio for accurate differential signal amplification
- Low input bias current suitable for high-impedance source applications
- Precision performance with low input offset voltage
Applications
- Precision data acquisition systems
- Medical equipment signal conditioning
- Industrial process control instrumentation
Procurement Notes
Verify the specific suffix 'AP' corresponds to the required commercial temperature grade (-40°C to +85°C) and PDIP-8 through-hole packaging. Confirm that the 110dB CMRR meets system requirements, as higher grades may exist. Ensure the single-channel configuration aligns with circuit design needs before ordering.
Selection Notes
Select this component when high accuracy and low drift are critical for small differential signals. The 1MHz bandwidth supports moderate-speed applications. Consider the 8-pin DIP package for prototyping or legacy board compatibility. Evaluate if the 125µV offset voltage is sufficient for the target application's noise floor.
Part Context
The INA114 belongs to Texas Instruments' family of general-purpose instrumentation amplifiers. It utilizes a three-op-amp architecture to provide high input impedance and excellent DC accuracy. This specific part number denotes the standard commercial grade version in a plastic dual in-line package, distinct from military or extended temperature variants.
Replacement Considerations
Check for direct pin-compatible replacements within the INA114 series or similar TI instrumentation amplifiers such as the INA114AU for surface mount options. Verify that substitute parts maintain the 110dB CMRR and 125µV offset voltage specifications to ensure circuit performance parity.
