OPA2832

OPA830 SBOS263B − AUGUST 2004 − REVISED JANUARY 2005 Low-Power, Single-Supply, Wideband Operational Amplifier FEATURES D D D D D D D D HIGH BANDWIDTH: 250MHz (G = +1) 110MHz (G = +2) LOW SUPPLY CURRENT: 3.9mA (VS = +5V) FLEXIBLE SUPPLY RANGE: ±1.4V to ±5.5V Dual Supply +2.8V to +11V Single Supply INPUT RANGE INCLUDES GROUND ON SINGLE SUPPLY 4.88V OUTPUT SWING ON +5V SUPPLY HIGH SLEW RATE: 550V/ns LOW INPUT VOLTAGE NOISE: 9.2nV/√Hz Pb-FREE SOT23 PACKAGE DESCRIPTION The OPA830 is a low-power, single-supply, wideband, voltage-feedback amplifier designed to operate on a single +3V or +5V supply. Operation on ±5V or +10V supplies is also supported. The input range extends below the negative supply and to within 1.7V of the positive supply. Using complementary common-emitter outputs provides an output swing to within 25mV of either supply while driving 150Ω. High output drive current (±80mA) and low differential gain and phase errors also make them ideal for single-supply consumer video products. Low distortion operation is ensured by the high gain bandwidth product (110MHz) and slew rate (550V/µs), making the OPA830 an ideal input buffer stage to 3V and 5V CMOS ADCs. Unlike other low-power, single-supply amplifiers, distortion performance improves as the signal swing is decreased. A low 9.2nV/√Hz input voltage noise supports wide dynamic range operation. The OPA830 is available in an industry-standard SO-8 package. The OPA830 is also available in an ultra-small SOT23-5 package. ...
