ADA4870ARRZ

高速运算放大器 Single Channel High Speed

High Speed, High Voltage,  1 A Output Drive Amplifier

GENERAL DESCRIPTION ADA4870ARRZ

The ADA4870 is a unity gain stable, high speed current feedback amplifier capable of delivering 1 A of output current and 2500 V/μs slew rate from a 40 V supply. Manufactured using the Analog Devices, Inc., proprietary high voltage extra fast complementary bipolar (XFCB) process, the innovative architecture of the ADA4870 enables high output power, high speed signal processing solutions in applications that require driving a low impedance load.
