DESCRIPTION:

The MSK 121(B) is a low cost monolithlic dual bridge amplifier capable of delivering 60 watts per package and is

available in many preset gain configurations. Internal RC snubber networks ensure stable operation and an internal

current limit of 4 amps improves product reliability under abnormal loading conditions. The MSK 121 Series can be

powered from a split supply of ±2.5V to ±20V or single ended from 5V to 40V. A minimum of 3 amps of load

current is available and the highly efficient driver section allows the output to swing to within 2.2 volts of the power

supply rail when delivering 2.5 amps of load current. The MSK 121 Series is packaged in a hermetically sealed 8-pin

TO-3 packae that can be attached directly to a heat sink for maximum thermal efficiency. Consult factory for

alternate package configurations.
