Delivering over 1 A output current, 40 V Model ADA4870 provides wide bandwidth of 52 MHz and slew rate of 2,500 V/µs to facilitate high-voltage pulses necessary to drive piezoelectric transducer in high-intensity focused ultrasound for medical treatment and procedures. In small-cell base stations and compact military radios, op amp assists with drive of power amplifier’s low impedance bias control to track envelope of RF signal, only using as much power for PA as needed to pass signal.
