RF Receivers
The outstanding bandwidth of 800 MHz along with 1200 V/µs of slew rate make the AD8001 useful in many general-purpose
GENERAL DESCRIPTION
The AD8001 is a low power, high speed amplifier designed high speed applications where dual power supplies of up to ± 6 V to operate on ± 5 V supplies. The AD8001 features unique and single supplies from 6 V to 12 V are needed. The AD8001 is available in the industrial temperature range of –40°C to +85°C.
