AUDIO OPERATIONAL AMPLIFIERS  
FEATURES  
SUPERIOR SOUND QUALITY  
ULTRA LOW DISTORTION: 0.00008%  
LOW NOISE: 8nV/Hz  
DESCRIPTION  
The OPA134 series are ultra-low distortion, low noise  
operational amplifiers fully specified for audio appli-  
cations. A true FET input stage was incorporated to  
provide superior sound quality and speed for excep-  
tional audio performance. This in combination with  
high output drive capability and excellent dc perfor-  
mance allows use in a wide variety of demanding  
applications. In addition, the OPA134’s wide output  
swing, to within 1V of the rails, allows increased  
headroom making it ideal for use in any audio circuit.  
TRUE FET-INPUT: IB = 5pA  
HIGH SPEED:  
SLEW RATE: 20V/µs  
BANDWIDTH: 8MHz  
HIGH OPEN-LOOP GAIN: 120dB (600)  
WIDE SUPPLY RANGE: ±2.5V to ±18V  
SINGLE, DUAL, AND QUAD VERSIONS  
OPA134 op amps are easy to use and free from phase  
inversion and overload problems often found in com-  
mon FET-input op amps. They can be operated from  
±2.5V to ±18V power supplies. Input cascode cir-  
cuitry provides excellent common-mode rejection and  
maintains low input bias current over its wide input  
voltage range, minimizing distortion. OPA134 series  
op amps are unity-gain stable and provide excellent  
dynamic behavior over a wide range of load condi-  
tions, including high load capacitance. The dual and  
quad versions feature completely independent cir-  
cuitry for lowest crosstalk and freedom from interac-  
tion, even when overdriven or overloaded.  
APPLICATIONS  
PROFESSIONAL AUDIO AND MUSIC  
LINE DRIVERS  
LINE RECEIVERS  
MULTIMEDIA AUDIO  
ACTIVE FILTERS  
Single and dual versions are available in 8-pin DIP  
and SO-8 surface-mount packages in standard con-  
figurations. 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.
