PRODUCT DESCRIPTION

The AD8041 is a low power voltage feedback, high speed ampli-

fier designed to operate on +3 V, +5 V, or

±5 V supplies. It has

true single-supply capability with an input voltage range extending

200 mV below the negative rail and within 1 V of the positive rail.

The output voltage swing extends to within 50 mV of each rail,

providing the maximum output dynamic range. Additionally, it

features gain flatness of 0.1 dB to 30 MHz while offering differ-

ential gain and phase error of 0.03% and 0.03

° on a single 5 V

supply. This makes the AD8041 ideal for professional video

electronics such as cameras, video switchers, or any high speed

portable equipment. The AD8041’s low distortion and fast settling

make it ideal for buffering high speed A-to-D converters.

The AD8041 has a high speed disable feature useful for mul-

tiplexing or for reducing power consumption (1.5 mA). The

disable logic interface is compatible with CMOS or open-

collector logic. The AD8041 offers a low power supply current

of 5.8 mA maximum and can run on a single 3 V power supply.

These features are ideally suited for portable and battery-

powered applications where size and power are critical.

The wide bandwidth of 160 MHz along with 160 V/

µs of slew

rate on a single 5 V supply make the AD8041 useful in many

general-purpose high speed applications where dual power

supplies of up to

±6 V and single supplies from 3 V to 12 V are

needed. The AD8041 is available in 8-lead PDIP and SOIC

over the industrial temperature range of –40

°C to +85°C.
