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: IB = 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.
