Product Details

The ADA4098-1 is a robust, precision, rail-to-rail input/output operational amplifier (op amp) with inputs that can operate from −VS to +VS and beyond, which is referred to in this document as Over-The-Top. The device has offset voltages <25 μV and input bias currents (IB) <700 pA and can operate on single or split supplies that range from 3 V to 50 V. The ADA4098-1 draws 165 μA of quiescent current.

The ADA4098-1 Over-The-Top input stage has robust input protection features for abusive environments. The inputs can tolerate up to 80 V of differential voltage without damage or degradation to dc accuracy. The operating input common-mode range extends from rail-to-rail and beyond; up to 70 V > –VS, independent of the +VS supply.

The ADA4098-1 is unity-gain stable and can drive loads requiring up to 20 mA, as well as driving capacitive loads as large as 200 pF. The amplifier is available with low power shutdown.

The ADA4098-1 is available in the standard, 6-lead, thin small outline transistor (TSOT) package.

Applications

  • Industrial sensor conditioning
  • Supply current sensing
  • Battery and power supply monitoring
  • Front-end amplifiers in abusive environments
  • 4 mA to 20 mA transmitters
