产品详情

The ADA4097-1 is a robust, precision, rail-to-rail input and output operational amplifier (op amp) with inputs that operate from −VS to +VS and beyond, which is referred to in this data sheet as Over-The-Top™. The device features offset voltages of <60 μV, input bias currents (IB) of <0.3 nA, and can operate on single or split supplies that range from 3 V to 50 V. The ADA4097-1 draws 32.5 μA of supply current.

The ADA4097-1 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 common-mode input range extends from rail-to-rail and beyond, up to 70 V > –VS, independent of the +VS supply.

The ADA4097-1 is unity-gain stable and can drive loads requiring up to 20 mA. The device can also drive capacitive loads as large as 200 pF. The amplifier is available with low power shutdown.

The ADA4097-1 is available in a 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
