OPAx134 SoundPlus™ High Performance Audio Operational Amplifiers

1 Features

3 Description

The OPA134 series are ultra-low distortion, low-noise

operational amplifiers fully specified for audio

applications. A true FET input stage is incorporated to

provide superior sound quality and speed for

exceptional audio performance. This, in combination

with high output drive capability and excellent DC

performance, allows for use in a wide variety of

demanding applications. In addition, the OPA134 has

a wide output swing, to within 1 V of the rails,

allowing increased headroom and making it ideal for

use in any audio circuit.

Superior Sound Quality

Ultra Low Distortion: 0.00008%

Low Noise: 8 nV/√Hz

True FET-Input: I_B= 5pA

High Speed:

–

Slew Rate: 20 V/µs

Bandwidth: 8 MHz

•

High Open-Loop Gain: 120 dB (600 Ω)

Wide Supply Range: ±2.5 V to ±18 V

Single, Dual, and Quad Versions

The OPA134 SoundPlus™ audio operational

amplifiers are easy to use and free from phase-

inversion and the overload problems often found in

common FET-input operational amplifiers. They can

be operated from ±2.5-V to ±18-V power supplies.

Input cascode circuitry provides excellent common-

mode rejection and maintains low input bias current

over its wide input voltage range, minimizing

distortion. OPA134 series operational amplifiers are

unity-gain stable and provide excellent dynamic

behavior over a wide range of load conditions,

including high load capacitance. The dual and quad

versions feature completely independent circuitry for

lowest crosstalk and freedom from interaction, even

when overdriven or overloaded.

THD+Noise vs Frequency

Single and dual versions are available in 8-pin DIP

and SO-8 surface-mount packages in standard

configurations. The quad is available in 14-pin DIP

and SO-14 surface mount packages. All are specified

for –40°C to 85°C operation. A SPICE macromodel is

available for design analysis.
