SBOS350A – DECEMBER 2006 – REVISED MAY 2008 Quad, Low-Power, Single-Supply, Wideband Operational Amplifier 2 • HIGH BANDWIDTH: The OPA4830 is a quad, low-power, single-supply, 280MHz (G = +1) wideband, voltage-feedback amplifier designed to 120MHz (G = +2) operate on a single +3V or +5V supply. Operation on • LOW SUPPLY CURRENT: ±5V or +10V supplies is also supported. The input 3.9mA/ch (VS = +5V) range extends below the negative supply and to • FLEXIBLE SUPPLY RANGE: within 1.8V of the positive supply. Using ±1.4V to ±5.5V Dual Supply complementary common-emitter outputs provides an output swing to within 220mV of either supply while +2.8V to +11V Single Supply driving 150 Ω. High output drive current (±80mA) and • INPUT RANGE INCLUDES GROUND ON low differential gain and phase errors also make this SINGLE SUPPLY amplifier an excellent choice for single-supply • 4.91V OUTPUT SWING ON +5V SUPPLY consumer video products. • HIGH SLEW RATE: 560V/µs Low distortion operation is ensured by the high gain • LOW INPUT VOLTAGE NOISE: 9.2nV/√Hz bandwidth product (110MHz) and slew rate (560V/ µs), making the OPA4830 an ideal input buffer • AVAILABLE IN A TSSOP-14 PACKAGE stage to 3V and 5V CMOS analog-to-digital converters (ADCs). Unlike other low-power, single-supply amplifiers, distortion performance • SINGLE-SUPPLY ANALOG-TO-DIGITAL improves as the signal swing is decreased. A low CONVERTER (ADC) INPUT BUFFERS 9.2nV/ √Hz input voltage noise supports wide dynamic • SINGLE-SUPPLY VIDEO LINE DRIVERS range operation. • CCD IMAGING CHANNELS The OPA4830 is available in an industry-standard • ACTIVE FILTERS quad pinout TSSOP-14 package. • PLL INTEGRATORS • PORTABLE CONSUMER ELECTRONICS DESCRIPTION SINGLES DUALS TRIPLES QUADS Rail-to-Rail OPA830 OPA2830 — — Rail-to-Rail Fixed-Gain OPA832 OPA2832 OPA3832 — General-Purpose OPA690 OPA2690 OPA3690 — (1800V/ µs slew rate) Low-Noise, OPA820 OPA2822 — OPA4820 High DC Precision Figure 1.
