Product Overview

The INA128P is a low power, general purpose Instrumentation Amplifier offers excellent accuracy. The versatile 3 operational amplifier design and small size make them ideal for a wide range of applications. Current-feedback input circuitry provides wide bandwidth even at high gain (200kHz at G = 100). A single external resistor sets any gain from 1 to 10,000. The INA128P provides an industry-standard gain equation. The INA128P is laser trimmed for very low offset voltage (50µV), drift (0.5µV/°C) and high common-mode rejection (120dB at G ≥100). It operates with power supplies as low as ±2.25V and quiescent current is only 700µA - ideal for battery-operated systems. Internal input protection can withstand up to ±40V without damage.
  • 50µV Maximum low offset voltage
  • 0.5µV/°C Maximum low drift
  • 5nA Maximum low input bias current
  • 120dB Minimum high CMR
  • Inputs protected to ±40V
  • 700µA Low quiescent current
  • Green product and no Sb/Br
