Checking for live stock

The INA126PA from Texas Instruments is a precision instrumentation amplifier engineered for accurate differential measurement in sensor, data-acquisition, and industrial instrumentation systems. With a very low input offset (max 250 µV), minimal bias current, and a wide supply range from 2.7 V to 36 V, it enables high-gain configurations (5 V/V to 10 000 V/V) with a single external resistor.

Crucial Features and Benefits of Choosing the Texas Instruments Instrumentation Amplifier

  • Low quiescent current (~175 µA) for energy-efficient operation.
  • Wide supply range – single- or dual-supply from ±1.35 V to ±18 V (i.e., 2.7 V to 36 V) enables use in diverse systems.
  • Excellent precision specs: input offset ≤ 250 µV, drift ≤ 3 µV/°C, and noise ~35 nV/√Hz typ.
  • High input impedance and good common-mode rejection make it suitable for sensor front-ends.
  • Through-hole 8-pin PDIP package (INA126PA) enables prototype or legacy board usage.

Optimised for High-Accuracy Signal Acquisition and Conditioning

The INA126PA is designed for demanding measurement applications where stability and precision matter. Its low offset and drift allow it to resolve small differential signals superimposed on large common-mode voltages. The capability to operate from a single or dual supply adds flexibility in instrumentation, medical, or portable systems.

Broad Range Application

  • Differential sensor signal amplification (e.g., strain gauges, bridge sensors).
  • Data acquisition front-end in instrumentation, medical, or industrial systems.
  • Precision signal conditioning in portable or battery-powered devices.
  • Any application requiring high gain, low drift, and accurate measurement of small voltages.
