The OPA1604AID is a SoundPlus high-performance bipolar-input Operational Amplifier for use with analog and digital mixers. It achieves very low 2.5nV/√Hz noise density with an ultralow distortion of 0.00003% at 1kHz. The OPA1604 series op amp offers rail-to-rail output swing to within 600mV with 2kR load, which increases headroom and maximizes dynamic range. This device also has a high output drive capability of ±30mA. This device operates over a very wide supply range of ±2.25 to ±18V, on only 2.6mA of supply current per channel. It is unity-gain stable and provide excellent dynamic behaviour over a wide range of load conditions. This device also features completely independent circuitry for lowest crosstalk and freedom from interactions between channels, even when overdriven or overloaded.
