Overview

BurrĆBrown Products from Texas Instruments ¨ OPA4830 SBOS350 – DECEMBER 2006 Quad, Low-Power, Single-Supply, Wideband Operational Amplifier FEATURES • HIGH BANDWIDTH: 280MHz (G = +1) 120MHz (G = +2) LOW SUPPLY CURRENT: 3.
9mA/ch (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.
91V OUTPUT SWING ON +5V SUPPLY HIGH SLEW RATE: 560V/µs LOW INPUT VOLTAGE NOISE: 9.
2nV/√Hz AVAILABLE IN A TSSOP-14 PACKAGE DESCRIPTION The OPA4830 is a quad, 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.
8V of the positive supply.
Using complementary common-emitter outputs provides an output swing to within 220mV of either supply while driving 150Ω.
High output drive current (±80mA) and low differential gain and phase errors also make this amplifier an excellent choice for single-supply consumer video products.
Low distortion operation is ensured by the high gain bandwidth product (110MHz) and slew rate (560V/µs), making the OPA4830 an ideal input buffer stage to 3V and 5V CMOS analog-to-digital converters (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 OPA4830 is available in an industry-standard quad pinout TSSOP-14 package.
