Texas Instruments OPA1652 / OPA1654 SoundPLUS™ Audio Op Amps

Texas Instruments OPA1652 (Dual) and OPA1654 (Quad) SoundPLUS™ FET-Input Operational Amplifiers (Op Amps) achieve a low 4.5nV/√Hz noise density with an ultralow distortion of 0.00005% at 1kHz. TI OPA1652 and OPA1654 op amps offer rail-to-rail output swing to within 800mV with a 2kΩ load for increased headroom and maximized dynamic range. These TI devices also have a high output drive capability of ±30mA. OPA1652 and OPA1654 op amps operate over a wide supply range of ±2.25V to ±18V or +4.5V to +36V on only 2mA of supply current per channel. Texas Instruments OPA1652 and OPA1654 op amps are unity-gain stable and provide excellent dynamic behavior over a wide range of load conditions. These devices also feature completely independent circuitry for lowest crosstalk and freedom from interactions between channels, even when overdriven or overloaded.
