DESCRIPTION

· The OPAx134 series (OPA134, OPA2134, OPA4134) are ultra-low distortion, low-noise operational amplifiers designed for audio applications.

· Features a true FET input stage for excellent sound quality and speed.

· High output drive capability and excellent DC performance make them suitable for demanding applications.

· Wide output swing, within 1V of the rails, increases headroom.

· Unity-gain stable with excellent dynamic behavior across various load conditions.

· Dual and quad versions have independent circuitry for low crosstalk and no interaction when overdriven or overloaded.

· Available in single (8-pin DIP, SO-8), dual (8-pin DIP, SO-8), and quad (SO-14) packages.

· Operates from ±2.5V to ±18V power supplies, specified for -40°C to +85°C.

FEATURES

· Excellent sound quality with ultra-low distortion (0.00008%) and low noise (8nV/√Hz).

· True FET-input with 5pA input bias current.

· High speed: 20V/µs slew rate and 8MHz bandwidth.

· High open-loop gain: 120dB (2kΩ).

· Wide supply range: ±2.5V to ±18V.

· Available in single, dual, and quad versions.

APPLICATIONS

· Professional audio and music equipment.

· Line drivers and receivers.
