Dual, Wideband, Low-Noise

Operational Amplifier

FEATURES

DESCRIPTION

● LOW INPUT NOISE VOLTAGE: 2.0nV/√Hz

The OPA2822 offers very low 2.0nV/√Hz input noise in a

wideband, unity-gain stable, voltage-feedback architecture.

Intended for xDSL receiver applications, the OPA2822 also

supports this low input noise with exceptionally low harmonic

distortion, particularly in differential configurations. Adequate

output current is provided to drive the potentially heavy load

of a passive filter between this amplifier and the codec.

Harmonic distortion for a 2V_PPdifferential output operating

from +5V to +12V supplies is ≤ –100dBc through 1MHz input

frequencies. Operating on a low 4.8mA/ch supply current,

the OPA2822 can satisfy all xDSL receiver requirements

over a wide range of possible supply voltages—from a single

+5V condition, to ±5V, up to a single +12V design.

● HIGH UNITY GAIN BANDWIDTH: 500MHz

●

HIGH GAIN BANDWIDTH PRODUCT: 240MHz

● HIGH OUTPUT CURRENT: 90mA

● SINGLE +5V TO +12V OPERATION

● LOW SUPPLY CURRENT: 4.8mA/ch

APPLICATIONS

● xDSL DIFFERENTIAL LINE RECEIVERS

● HIGH DYNAMIC RANGE ADC DRIVERS

● LOW NOISE PLL INTEGRATORS

● TRANSIMPEDANCE AMPLIFIERS

● PRECISION BASEBAND I/Q AMPLIFIERS

● ACTIVE FILTERS

General-purpose applications on a single +5V supply will

benefit from the high input and output voltage swing available

on this reduced supply voltage. Low-cost precision integra-

tors for PLLs will also benefit from the low voltage noise and

offset voltage. Baseband I/Q receiver channels can achieve

almost perfect channel match with noise and distortion to

support signals through 5MHz with > 14-bit dynamic range.
