Application Notes

  • AC Coupling Instrumentation and Difference Amplifiers
    PDF, 38 Kb, File published: Sep 27, 2000
    The need to glean AC signals from DC in the presence of common-mode noise frequently occurs in signal conditioning applications. AC coupling to an instrumentation amplifier (IA) or difference amplifier can be used to accurately extract the AC signal while rejecting DC and common-mode noise.
  • Single-Supply Operation of Isolation Amplifiers
    PDF, 46 Kb, File published: Sep 27, 2000
    For simplicity, many systems are designed to operate from a single external power supply. In battery powered systems such as aircraft and automotive, it's often a requirement. Isolation amplifiers such as the ISO120 and ISO122 can be easily modified for input side single-supply operation with the addition of an INA105 difference amplifier. With ISO amps, it's the isolated input side power supply w
  • Extending the Common-Mode Range of Difference Amplifiers
    PDF, 49 Kb, File published: Sep 27, 2000
    Extending the common-mode range of difference amplifiers allows their use in a wider variety of reduced power-supply applications. The INA117 has a specified common-mode input range of В±200V when operating on standard В±15V power supplies. At power-supply voltages above В±13V, the INA117 input range is limited to В±200V by the power capabilities of its internal input resis
  • Simple Circuit Delivers 38Vp-p at 5A from 28V Unipolar Supply
    PDF, 26 Kb, File published: Sep 27, 2000
    Since the first analog IC requiring bipolar supplies was developed, people have been trying to operate them from unipolar supplies. Not only do the headroom (VS - VOUTMAX) requirements come into play, but with a unipolar supply typically come unipolar outputs. To get bipolar output swings from a unipolar supply, drive the load differentially and create a reference signal wh
  • Level Shifting Signals with Differential Amplifiers
    PDF, 23 Kb, File published: Sep 27, 2000
    The INA105 is a unity gain differential amplifier consisting of a premium grade operational amplifier and an on-chip precision resistor network. The self-contained INA105 makes it ideal for many applications. One such application is precision level shifting.
  • Boost Amplifier Output Swing With Simple Modification
    PDF, 46 Kb, File published: Sep 27, 2000
    In many applications it is desirable for the output of an amplifier to swing close to its power supply rails. Most amplifiers only guarantee an output swing of В±10V to В±12V when operating on standard В±15V power supplies. With the addition of four resistors and a pair of garden-variety transistors, the INA105 or INA106 difference amplifiers can be modified to provide nearly a f
