    SBOS058A – DECEMBER 1997 – REVISED OCTOBER 2015 OPAx134 SoundPlus™ High Performance Audio Operational Amplifiers
    1 Features 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. 1 Superior Sound Quality
    Ultra Low Distortion: 0.00008%
    Low Noise: 8 nV/в€љHz

    Remove the DC Portion of Signals with the ADS7817
    Unwanted portions of a signal, such as a DC pedestal, can be difficult to reject in a single supply circuit. A DC pedestal voltage most typically appears at the output of an operational amplifier with a small signal riding on top of it. This pedestal voltage is required in the analog domain to insure that the small signal that contains the pertinent information never falls below the ground potenti

    Precision Absolute Value Circuits
    You can build a precision absolute value circuit using two op amps and two precision resistors. If you use an op amp and an IC difference amplifier, no user supplied precision resistors or resistor adjustments are required. Circuits shown are suitable for precision split supply operation and for single-supply operation. When used with a rail-to-rail op amp, the single supply circuit can approach a

    Compensate Transimpedance Amplifiers Intuitively (Rev. A)
    Transimpedance amplifiers are used to convert low-level photodiode currents to usable voltage signals. All too often, the amplifiers have to be empirically compensated to operate properly. The problem can be easily understood if one looks at all the elements involved.

    Tuning in Amplifiers
    Have you ever had the experience of designing an analog gain block with an amplifier that is specified to be unity gain stable only to find that it is oscillating out of control in your circuit? Or have you ever replaced a stable voltage feedback amplifier with a current feedback amplifier to find that the current feedback amplifier immediately oscillates when placed in the amplifier socket? Oscil

    Single-Supply Operation of Operational Amplifiers
    Operation of op amps from single supply voltages is useful when negative supply voltages are not available. Furthermore, certain applications using high voltage and high current op amps can derive important benefits from single supply operation.

    Op Amp Performance Analysis
    This bulletin reflects the analysis power gained through knowledge of an op amp circuit's feedback factor. Feedback dictates the performance of an op amp both in function and in quality. The major specifications of the amplifier descibe an open-loop device awaiting feedback direction of the end circuit's function. Just how well the amplifier performs the function reflects through the feedback inte
