Dual 160 MHz Rail-to-Rail Amplifier AD8042 FEATURES CONNECTION DIAGRAM Single AD8041 and quad AD8044 also available +V 1 8 S OUT1 Fully specified at +3 V, +5 V, and 5 V supplies Output swings to within 30 mV of either rail OUT2 IN1 2 7 Input voltage range extends 200 mV below ground IN2 +IN1 3 6 No phase reversal with inputs 0.5 V beyond supplies V 4 S 5 +IN2 Low power of 5.2 mA per amplifier AD8042 High speed and fast settling on 5 V Figure 2. 8-Lead PDIP and 8-Lead SOIC N 160 MHz, 3 dB bandwidth (G = +1) 200 V/s slew rate The output voltage swing extends to within 30 mV of each rail, 39 ns settling time to 0.1% providing the maximum output dynamic range. Additionally, it Good video specifications (RL = 150 , G = +2) features gain flatness of 0.1 dB to 14 MHz while offering differential Gain flatness of 0.1 dB to 14 MHz gain and phase error of 0.04% and 0.06 on a single 5 V supply. 0.02% differential gain error This combination of features makes the AD8042 useful for 0.04 differential phase error professional video electronics, such as cameras, video switchers, Low distortion: 64 dBc worst harmonic 10 MHz or any high speed portable equipment. The low distortion and Drives 50 mA 0.5 V from supply rails fast settling of the AD8042 make it ideal for buffering single- supply, high speed analog-to-digital converters (ADCs). APPLICATIONS The AD8042 offers a low power supply current of 12 mA Video switchers maximum and can run on a single 3.3 V power supply. These Distribution amplifiers features are ideally suited for portable and battery-powered Analog-to-digital drivers applications where size and power are critical. Professional cameras CCD Imaging systems The wide bandwidth of 160 MHz along with 200 V/s of slew Ultrasound equipment (multichannel) rate on a single 5 V supply make the AD8042 useful in many general-purpose, high speed applications where single supplies from +3.3 V to +12 V and dual power supplies of up to 6 V are GENERAL DESCRIPTION needed. The AD8042 is available in 8-lead PDIP and 8-lead The AD8042 is a low power voltage feedback, high speed amplifier SOIC N packages. designed to operate on +3 V, +5 V, or 5 V supplies. It has true 15 single-supply capability with an input voltage range extending V = 5V S 12 G = +1 200 mV below the negative rail and within 1 V of the positive rail.
