160 MHz Rail-to-Rail Amplifier with Disable AD8041 FEATURES CONNECTION DIAGRAM Fully Specified for +3 V, +5 V, and 5 V Supplies 8-Lead PDIP, CERDIP and SOIC Output Swings Rail to Rail Input Voltage Range Extends 200 mV Below Ground 1 8 No Phase Reversal with Inputs 1 V Beyond Supplies NC DISABLE Disable/Power-Down Capability INPUT 2 7 V S Low Power of 5.2 mA (26 mW on 5 V) 3 6 OUTPUT INPUT High Speed and Fast Settling on 5 V: AD8041 V 4 5 NC S (Top View) 160 MHz 3 dB Bandwidth (G = +1) NC = NO CONNECT 160 V/ s Slew Rate 30 ns Settling Time to 0.1% The output voltage swing extends to within 50 mV of each rail, Good Video Specifications (R = 150 , G = +2) L providing the maximum output dynamic range. Additionally, it Gain Flatness of 0.1 dB to 30 MHz features gain flatness of 0.1 dB to 30 MHz while offering differ- 0.03% Differential Gain Error ential gain and phase error of 0.03% and 0.03 on a single 5 V 0.03 Differential Phase Error supply. This makes the AD8041 ideal for professional video Low Distortion electronics such as cameras, video switchers, or any high speed 69 dBc Worst Harmonic 10 MHz portable equipment. The AD8041s low distortion and fast settling Outstanding Load Drive Capability make it ideal for buffering high speed A-to-D converters. Drives 50 mA 0.5 V from Supply Rails The AD8041 has a high speed disable feature useful for mul- Cap Load Drive of 45 pF tiplexing or for reducing power consumption (1.5 mA). The APPLICATIONS disable logic interface is compatible with CMOS or open- Power Sensitive High Speed Systems collector logic. The AD8041 offers a low power supply current Video Switchers of 5.8 mA maximum and can run on a single 3 V power supply. Distribution Amplifiers These features are ideally suited for portable and battery- A/D Drivers powered applications where size and power are critical. Professional Cameras The wide bandwidth of 160 MHz along with 160 V/s of slew CCD Imaging Systems rate on a single 5 V supply make the AD8041 useful in many Ultrasound Equipment (Multichannel) general-purpose high speed applications where dual power Single-Supply Multiplexer 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 PRODUCT DESCRIPTION over the industrial temperature range of 40C to +85C. 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 2 true single-supply capability with an input voltage range extending V = 5V S 1 G = +2 200 mV below the negative rail and within 1 V of the positive rail.
