FAQs

What is INA2128UA?

The INA2128UA is a precision, low-power, instrumentation amplifier designed by Texas Instruments. It is well-suited for applications requiring accurate signal amplification, such as sensor interfaces, industrial instrumentation, and data acquisition systems.

How Does INA2128UA Work?

The INA2128UA operates as an instrumentation amplifier, providing high input impedance, low noise, and excellent common-mode rejection. It amplifies the differential input signal while rejecting common-mode signals, making it ideal for measuring small differential signals in the presence of noise.

How Many Pins does INA2128UA have and What are the Functions of the Pinout Configuration?

The INA2128UA is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:

  • V+: Positive power supply pin.
  • V-: Negative power supply pin.
  • IN+: Non-inverting input pin.
  • IN-: Inverting input pin.
  • REF-: Reference pin for setting the output common-mode voltage.
  • OUT: Output pin for the amplified signal.

What are the Pros and Cons of INA2128UA?

Pros:

  • Precision: Offers high accuracy and stability for signal amplification.
  • Low Power Consumption: Operates at low power levels, suitable for battery-powered devices.
  • Excellent Common-Mode Rejection: Helps in rejecting noise and interference for clean signal amplification.
  • High Input Impedance: Provides a high input impedance for accurate measurement of small signals.
  • Small Package: The 8-pin SOIC package is compact and space-efficient.

Cons:

  • Limited Bandwidth: May have a limited bandwidth compared to some high-speed amplifiers.
  • External Components: May require additional components for specific applications or filtering requirements.
