3000 V/, 35W Current Feedback Quad Amplifier

The AD8004 is a quad, low power, high speed amplifier designed to operate on single or dual supplies. It utilizes a current feedback architecture and features high slew rate of 3000 V/µs making the AD8004 ideal for handling large amplitude pulses. Additionally, the AD8004 provides gain flatness of 0.1 dB to 30 MHz while offering differential gain and phase error of 0.04% and 0.10°. This makes the AD8004 suitable for video electronics such as cameras and video switchers.

The AD8004 offers low power of 3.5 mA/amplifier and can run on a single +4 V to +12 V power supply, while being capable of delivering up to 50 mA of load current. These features make this amplifier ideal for portable and battery powered applications where size and power are critical.

The outstanding bandwidth of 250 MHz along with 3000 V/µs of slew rate make the AD8004 useful in many general purpose, high speed applications where dual power supplies of up to feed ±6 V and single supplies from 4 V to 12 V are needed. The AD8004 is available in the industrial temperature range of –40°C to +85°C in a 14 lead SOIC package.
