The OPA2134UAE4 is a SoundPlus™ high performance audio Operational Amplifier, a true FET input stage is incorporated to provide superior sound quality and speed for exceptional audio performance. The OPA2134 has a wide output swing, to within 1V of the rails, allowing increased headroom and making it ideal for use in any audio circuit. The audio operational amplifier is easy to use and free from phase-inversion and the overload problems often found in common FET-input operational amplifiers. Input cascode circuitry provides excellent common-mode rejection and maintains low input bias current over its wide input voltage range, minimizing distortion. This operational amplifier has unity-gain stable and provide excellent dynamic behaviour 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.
The LF353M/NOPB is a dual wide bandwidth high speed JFET-input Operational Amplifier with an internally trimmed input offset voltage (BI-FET II technology). It requires low supply current yet maintains a large gain bandwidth product and fast slew rate. In addition, well matched high voltage JFET input device provides very low input bias and offset currents. The LF353-N is pin compatible with the standard LM1558 allowing designers to immediately upgrade the overall performance of existing LM1558 and LM358 designs. This amplifier may be used in applications such as high speed integrators, fast D/A converters, sample and hold circuits and many other circuits requiring low input offset voltage, low input bias current, high input impedance, high slew rate and wide bandwidth. The devices also exhibit low noise and offset voltage drift.
