DESCRIPTION:
MSK167
MSK166
The MSK 166 and 167 ultra high voltage monolithic MOSFET operational amplifier ideally suited for electrostatic
transducer and electrostatic deflection applications. With a total supply voltage rating of 350 volts and 60mA of
available output current, the MSK 166 and 167 are also an excellent low cost choice for high voltage piezo drive
circuits. The MOSFET output frees the MSK 166 and 167 from secondary breakdown limitations and power dissipa-
tion is kept to a minimum with a quiescent current rating of only 2mA. The MSK 166 is packaged in a hermetically
sealed 40 pin leadless chip carrier which has two external compensation pins. The output of the MSK 166 and 167
can be externally nulled using the two null pins. The MSK 167 is packaged in a 24 pin ceramic flatpack and is
otherwise identical to the MSK 166. (see mechanical specifications).
