ADA4870: High Speed, High Voltage, 1A Output Drive Amplifier - 1

High Speed, High Voltage, 1A Output Drive Amplifier Preliminary Technical Data Ideal for driving high capacitive or heavy resistive loads Wide supply range: 10 V to 40 V High output current drive: 1A Wide output voltage swing: 37 V swing with 40 V supply Large signal -3 dB BW: 45 MHz (VOUT = 20 V p-p, 300 pF load) High slew rate: 2500 V/us (peak) Short-circuit current protection Thermal overload protection & flag Piezo Driver Waveform Generation GENERAL DESCRIPTION The ADA4870 is a unity gain stable, high-speed current feedback amplifier capable of delivering 1A of continuous output current from a 40V supply. Manufactured on ADI's proprietary high voltage XFCB process, the innovative architecture of the ADA4870 enables high performance signal processing solutions in a variety of demanding applications. The ADA4870 is ideal for driving the gate of high voltage Power FETs, Piezo transducers, PIN diodes, CCD imagers and a variety of other demanding applications that require wide dynamic range from high supply voltage and high current CONNECTION DIAGRAM The ADA4870 is available in a Power SOIC package (PSOP_3), featuring an exposed thermal slug that provides high thermal conductivity to the PCB then heat sink enabling efficient heat transfer for improved reliability in demanding environments . The ADA4870 operates over the industrial temperature range (-40°C to +85°C) at maximum performance when appropriate thermal management techniques are applied.
