Overview
SA12 Pulse Width Modulation Amplifiers SAS1A122 FEATURE • HIGH FREQUENCY SWITCHING — 200 kHz • WIDE SUPPLY RANGE—16-200V • 15A CONTINUOUS TO 65°C CASE • 3 PROTECTION CIRCUITS • ANALOG OR DIGITAL INPUTS • SYNCHRONIZED OR EXTERNAL OSCILLATOR • FLEXIBLE FREQUENCY CONTROL APPLICATIONS • REACTIVE LOADS • LOW FREQUENCY SONAR • LARGE PIEZO ELEMENTS • OFF-LINE DRIVERS • C-D WELD CONTROLLER 12-PIN POWER DIP PACKAGE STYLE CR EXTERNAL CONNECTIONS DESCRIPTION The SA12 is a pulse width modulation amplifier that can supply 3000W to the load.
An internal 400kHz oscillator requires no external components.
The clock input stage divides the oscillator frequency by two, which provides the 200 kHz switching frequency.
External oscillators may also be used to lower the switching frequency or to synchronize multiple amplifiers.
Current sensing is provided for each half of the H-bridge giving amplitude and direction data.
A shutdown input turns off all four driv...
