80V-High Voltage Operational Amplifier
| The high voltage
operational amplifier PR2201 works for supply voltages of up to 80V
single supply or up to ±40V and a maximum output current of ±6mA.
The common mode input voltage covers nearly the complete supply voltage range with an excellent common mode and power supply rejection ratio of typical more than 110dB. 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. But also in audio applications
with higher supply voltages (f.e. in a microphone
preamplifier) this op amp can be used. |
