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.
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.
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.
