™ High-Performance, JFET-Input

AUDIO OPERATIONAL AMPLIFIERS

Check for Samples: OPA1641, OPA1642, OPA1644

FEATURES

DESCRIPTION

234

•

SUPERIOR SOUND QUALITY

The OPA1641 (single), OPA1642 (dual), and

OPA1644 (quad) series are JFET-input, ultralow

distortion, low-noise operational amplifiers fully

specified for audio applications.

•

TRUE JFET INPUT OP AMP

WITH LOW INPUT BIAS CURRENT

•

LOW NOISE: 5.1nV/√Hz at 1kHz

ULTRALOW DISTORTION: 0.00005% at 1kHz

HIGH SLEW RATE: 20V/ms

The OPA1641, OPA1642, and OPA1644 rail-to-rail

output swing allows increased headroom, making

these devices ideal for use in any audio circuit.

Features include 5.1nV/√Hz noise, low THD+N

(0.00005%), a low input bias current of 2pA, and low

quiescent current of 1.8mA per channel.

UNITY GAIN STABLE

NO PHASE REVERSAL

LOW QUIESCENT CURRENT:

1.8mA per Channel

These devices operate over a very wide supply

voltage range of ±2.25V to ±18V. The OPA1641,

OPA1642, and OPA1644 series of op amps are

unity-gain stable and provide excellent dynamic

behavior over a wide range of load conditions.

•

RAIL-TO-RAIL OUTPUT

WIDE SUPPLY RANGE: ±2.25V to ±18V

SINGLE, DUAL, AND QUAD VERSIONS

AVAILABLE

The dual and quad versions feature completely

independent circuitry for lowest crosstalk and

freedom from interactions between channels, even

when overdriven or overloaded.

APPLICATIONS

•

PROFESSIONAL AUDIO EQUIPMENT

ANALOG AND DIGITAL MIXING CONSOLES
