OPA830

SBOS263B − AUGUST 2004 − REVISED JANUARY 2005

Low-Power, Single-Supply, Wideband

Operational Amplifier

F_DEATURES

HIGH BANDWIDTH:

250MHz (G = +1)

110MHz (G = +2)

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 SUPPLY CURRENT: 3.9mA (V = +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

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. For fixed-gain line driver applications,

consider the OPA832.
