 OPA2134PA   High Performance
AUDIO OPERATIONAL AMPLIFIERS
FEATURES DESCRIPTION
● SUPERIOR SOUND QUALITY The OPA134 series are ultra-low distortion, low noise
● ULTRA LOW DISTORTION: 0.00008% operational amplifiers fully specified for audio applications.
● LOW NOISE: 8nV/√Hz A true FET input stage was incorporated to
● TRUE FET-INPUT: IB = 5pA provide superior sound quality and speed for exceptional
● HIGH SPEED: audio performance. This in combination with
SLEW RATE: 20V/µs high output drive capability and excellent dc performance
BANDWIDTH: 8MHz allows use in a wide variety of demanding
● HIGH OPEN-LOOP GAIN: 120dB (600Ω) applications. In addition, the OPA134's wide output
● WIDE SUPPLY RANGE: ±2.5V to ±18V swing, to within 1V of the rails, allows increased
● SINGLE, DUAL, AND QUAD VERSIONS 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
APPLICATIONS FET-input op amps. They can be operated from
● PROFESSIONAL AUDIO AND MUSIC ±2.5V to ±18V power supplies. Input cascode circuitry
● LINE DRIVERS provides excellent common-mode rejection and
● LINE RECEIVERS maintains low input bias current over its wide input
● MULTIMEDIA AUDIO voltage range, minimizing distortion. OPA134 series
● ACTIVE FILTERS op amps are unity-gain stable and provide excellent
● PREAMPLIFIERS dynamic behavior over a wide range of load conditions,
● INTEGRATORS including high load capacitance. The dual and
● CROSSOVER NETWORKS 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.
