Such characteristics are enhanced by wide output swing and load drive capability. A unique output stage permits output swing approaching the rail under moderate load conditions. Particularly well suited for computer audio systems and portable digital audio units, the SSM2135 can perform preamplification, headphone and speaker driving, and balanced line driving and receiving. Additionally, the device is ideal for input signal conditioning in single-supply, Σ-Δ, analog-todigital converter subsystems such as the AD1877.
