High Performance
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 (600Ω)
● 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.
