FEATURES High speed and fast settling on 5 V 110 MHz, −3 dB bandwidth (G = +1) (AD8051/AD8052) 150 MHz, −3 dB bandwidth (G = +1) (AD8054) 145 V/μs slew rate 50 ns settling time to 0.1% Single-supply operation Output swings to within 25 mV of either rail Input voltage range: −0.2 V to +4 V; VS = 5 V Video specifications (G = +2) 0.1 dB gain flatness: 20 MHz; RL = 150 Ω Differential gain/phase: 0.03%/0.03° Low distortion −80 dBc total harmonic @ 1 MHz, RL = 100 Ω Outstanding load drive capability Drives 45 mA, 0.5 V from supply rails (AD8051/AD8052) Drives 50 pF capacitive load (G = +1) (AD8051/AD8052) Low power: 2.75 mA/amplifier (AD8054) Low power: 4.4 mA/amplifier (AD8051/AD8052) APPLICATIONS Active filters A/D drivers Consumer video Professional cameras CCD imaging systems CD/DVD ROMs GENERAL DESCRIPTION The AD8051 (single), AD8052 (dual), and AD8054 (quad) are low cost, high speed, voltage feedback amplifiers. The amplifiers operate on +3 V, +5 V, or ±5 V supplies at low supply current. They have true single-supply capability with an input voltage range extending 200 mV below the negative rail and within 1 V of the positive rail. Despite their low cost, the AD8051/AD8052/AD8054 provide excellent overall performance and versatility. The output voltage swings to within 25 mV of each rail, providing maximum output dynamic range with excellent overdrive recovery. The AD8051/AD8052/AD8054 are well suited for video electronics, cameras, video switchers, or any high speed portable equipment. Low distortion and fast settling make them ideal for active filter applications.
