ADA4870ARRZ

• Product Introduction

ADA4870ARRZ a high-speed current feedback amplifier with stable unit gain

ADA4870 is a unity-gain-stable, high-speed current feedback amplifier capable of delivering 1 A output current and 2500 V/μs slew rate using a 40 V supply. ADA4870's innovative architecture is manufactured using Analog Devices' proprietary high-voltage ultra-fast complementary bipolarity (XFCB) process to provide high-output-power, high-speed signal processing solutions for applications that require low-impedance loads to be driven.

ADA4870 is ideal for driving high-voltage power FETistors, piezoelectric sensors, PIN diodes, CCD panels, and a variety of other demanding applications that require high speed of high supply voltage and high current output.

ADA4870 is available in a Power SOIC package (PSOP_3), which provides a high thermal conductivity exposed heat block for efficient heat dissipation, improving performance and reliability in demanding applications. ADA4870 has an operating temperature range of −40 °C to +85 °C industrial temperature range.
