80V High Voltage Op-Amp from PREMA

The output voltage can approximate the positive or negative supply voltage close to 1V. Precision applications, for example in automatic test environments, can be covered with the PR2201 due to a very low typical input bias current of 5pA and an input offset voltage of typical ±2mV, which can be further reduced by external trimming (only PR2201).

The temperature increase of the component remains small in spite of the high voltages due to the low quiescent current of only 500µA. Also fast control circuits may be designed with this PR2201 due to the gain bandwidth product of up to 1MHz and a slew rate of more than 1V/µs.
The wide common mode input range allows high impedance measurements of small differential voltages at high potentials, e.g. in Wheatstone bridges. Actors using higher voltages can be driven directly by the IC. The wide input voltage range together with a high differential input voltage of up to 60V make this circuit very suitable for applications with higher voltage spikes like in the automotive field.
