PWM Amplifier Provides 22 kHz Of Useable Bandwidth

The SA12 hybrid PWM amplifier provides 22 kHz of useable bandwidth for motor and piezo applications involving rapid motion and heavy loads. The device features a 200-kHz switching frrequency that steps down to a bandwidth of 22 kHz.Continuous output current is 15A and pulse current is 20A. The SA12 operates on a single supply of from 16V to 200V and is capable of delivering up to 3 kW into the load with an efficiency of 97%.To lower its switching frequency, the SA12 can be used with external oscillators or it can be synchronized with multiple amplifiers. Other features include a 12-pin hermetic MO-127 package requiring only three square inches of board space and bulit-in thermal protection.
