GENERAL DESCRIPTION
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.
The ADA4870 is ideal for driving high voltage power FETs, piezo transducers, PIN diodes, CCD panels, and a variety of other demanding applications that require high speed from high supply voltage at high output current.
The ADA4870 is available in a power SOIC package (PSOP_3), featuring an exposed thermal slug that provides high thermal conductivity, enabling efficient heat transfer for improved perfor mance and reliability in demanding applications. The ADA4870 operates over the industrial temperature range (−40°C to +85°C).
