Features ultra-low distortion (0.00008%), low noise, and wide bandwidth (8MHz). Used in audio preamps and DAC output stages.+A dual FET-input operational amplifier built for high-fidelity audio, in SOIC-8, from the Burr-Brown line. It reaches extremely low total harmonic distortion (0.00008%) with low noise and a fast 20 V/us slew rate, and the FET input keeps bias current tiny so it drives high-impedance sources cleanly. That makes it a favorite for preamps, active crossovers, DAC output stages, and headphone drivers where the LM358 or TL072 are not clean enough. Two independent amplifiers share the supply, which runs from split rails up to plus/minus 18 V.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | OUT A | output | Output of channel A op-amp. Drives external loads with rail-to-rail-1V swing; short-circuit protected (continuous). |+| 2 | -IN A | input | Inverting input of channel A op-amp. True FET input with IB = 5pA typ.
