Overview
The ADA4870ARRZ-RL is a high-speed current feedback amplifier manufactured by Analog Devices Inc. This unity gain stable amplifier is designed using the proprietary high voltage extra fast complementary bipolar (XFCB) process, enabling high output power and high speed signal processing. It is particularly suited for applications requiring the drive of low impedance loads, such as high voltage power FETs, piezo transducers, PIN diodes, and CCD panels. The ADA4870ARRZ-RL operates over the industrial temperature range of −40°C to +85°C and is available in a power SOIC package (PSOP_3) with an exposed thermal slug for efficient heat transfer.
