GENERAL DESCRIPTION
of slew rate make the AD8004 useful in many general-purpose, The AD8004 is a quad, low power, high speed amplifier designed high speed applications where dual power supplies of up to ±6 V to operate on single or dual supplies. It utilizes a current feed- and single supplies from 4 V to 12 V are needed. The AD8004 back architecture and features high slew rate of 3000 V/ms is available in the industrial temperature range of –40∞C to +85∞C in the R package. making the AD8004 ideal for handling large amplitude pulses. Additionally, the AD8004 provides gain flatness of 0.1 dB to
