Mainz, Germany, March
24, 2005
For the application in custom specific ICs, PREMA Semiconductor GmbH
has designed the new high voltage operational amplifier OP601VHV for
supply voltages of up to ±60V or up to 120V single supply.
The common mode input voltage covers nearly the complete supply
voltage range with a very good common mode and power supply
rejection ratio of more than 110dB. The output voltage can
approximate the positive or negative supply voltage as close as 1V.
The temperature increase of the component remains small in spite of
the high voltages due to the low quiescent current of only 180µA.
Fast control circuits may be designed with this OP601VHV due to the
gain bandwidth product of up to 3.5MHz and a slew rate of nearly
4V/µs.
The new high voltage operational amplifier OP601VHV has been
developed and produced with the enhanced semiconductor process ModuS
U6 by the ASIC specialist PREMA Semiconductor.
The OP601VHV can be used e.g. in a motor control circuit with
current sensing using a shunt resistor at high potential. 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
ASIC.
For the design of high voltage ASICs, PREMA offers linear
regulators, step-down converters and several output drivers. Several
externally connected components can be saved because high voltage
transistors and resistors can be integrated now into the ASIC.
