Robust, Low Power Amplifier Features Input Overvoltage Protection
The analog inputs to systems such as industrial programmable logic controllers can often include transient or fault voltages that exceed the safe input range of the front-end amplifiers. The ADA4091-2 is a 36 V, micropower, single-supply, rail-to-rail input/output operational amplifier with proprietary input protection circuitry which allows the inputs to exceed the supply rails by 10 V or more with no damage or phase reversal. External protection devices are not required, thereby reducing cost and space requirements.
The low power and small form factor make the ADA4091-2 ideal for both multichannel systems and space-constrained applications. Low offset, low offset drift, and wide bandwidth allow accurate signal conditioning of a wide variety of sensor inputs. In addition to the robust input overvoltage protection, the ADA4091-2 achieves outstanding resistance to electrostatic voltage discharges. With a Human Body Model (HBM) rating of >4 kV, the part is protected from potential damage during system manufacture and in field use, and also reduces or eliminates the need for additional external protection devices. It is available in 8-lead LFCSP and 8-lead SOIC packaging.
