DESCRIPTION

The OPA134 series are ultra-low distortion, low noise
operational amplifiers fully specified for audio appli­cations. A true FET input stage was 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 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.

OPA134 op amps are easy to use and free from phase
inversion and overload problems often found in com­mon 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 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.

ELECTROSTATIC
DISCHARGE SENSITIVITY

This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.

ESD damage can range from subtle performance degrada­tion to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet its
published specifications.
