Sound-Plus High-Performance, JFET-Input Audio OpAmps

The OPA1641 (single), OPA1642 (dual), and OPA1644 (quad) series are JFET-input, ultralow distortion, low-noise Operational Amplifiers fully specified for Audio applications. The OPA1641 OPA1642, and OPA1644 Rail-to-Rail output swing allows increased headroom, making these devices ideal for use in any Audio circuit. Features include 5.1nV/√Hz noise, low THD+N (0.00005%), a low input bias current of 2pA, and low quiescent current of 1.8mA per channel. These devices operate over a very wide supply voltage range of ±2.25V to ±18V. The OPA1641 OPA1642, and OPA1644 series of op amps are unity-gain stable and provide excellent dynamic behavior over a wide range of load conditions. The dual and quad versions feature completely independent circuitry for lowest crosstalk and freedom from interactions between channels, even when overdriven or overloaded. The OPA1641 OPA1642, and OPA1644 are specified from –40°C to +85°C. SoundPlus™ By Texas Instruments
