The Texas Instruments INA103KU is a high-performance, monolithic instrumentation amplifier designed for applications demanding outstanding precision and audio clarity. Built for engineers who refuse to compromise, it delivers ultra-low noise and distortion, achieving exceptional fidelity when amplifying low-level differential signals, such as balanced microphones or bridge transducers. With a built-in resistor-set gain structure and a robust dual-supply range (±18 V to ±50 V), this chip offers both simplicity and versatility. Its compact SOIC 16 package, wide temperature tolerance, and top-tier specifications make it a go-to choice for audio, measurement, and industrial-grade signal conditioning circuits.

What Benefits Do You Get?

When you choose the INA103KU, you're locking in unmatched signal integrity: ultra-low noise performance (~1 nV/√Hz), extremely low total harmonic distortion (~0.0009 % at 1 kHz, gain = 100), and excellent common mode rejection (>100 dB). This translates to clean, accurate amplification even in electrically noisy environments. You also benefit from a flexible gain setup (selectable G = 1 or 100 onboard, expandable via external resistor), wide operating supply voltage, robust output current, and thermally resilient packaging—all packaged in a compact, industry-standard footprint. Essentially, you get exceptional analog fidelity, design flexibility, and deployment confidence.

Product Functional Highlights:

  • Ultra-low noise performance (~1 nV/√Hz), ideal for amplifying low-level sources with minimal hiss or interference
  • Exceptionally low THD+N (~0.0009 % at 1 kHz, gain = 100) for clean audio and measurement applications
  • Wide gain bandwidth (approx. 100 MHz at G = 1000) enables precise, high frequency gain stages
  • Outstanding common mode rejection ratio (>100 dB) ensures accurate differential measurements in noisy settings
  • Built in gain selection resistors (fixed gain options G = 1 or 100), simplifying circuit design and reducing external components
  • Wide dual supply voltage range (±18 V to ±50 V) for powering demanding sensor or audio stages
  • Solid output drive capability (~40 mA), supporting heavier loads without additional buffering
  • Compact industry-standard SOIC 16 package (dimensions ~10.28 × 7.52 × 2.35 mm), compatible with surface-mount manufacturing.
