The analog portion of the AD1856 is fabricated with bipolar and MOS devices, as well as thin film resistors. This combination of circuit elements, as well as careful design and layout techniques, results in high performance audio playback. Laser trimming of the linearity error affords extremely low total harmonic distortion. An optional linearity trim pin is provided to allow residual differential linearity error at midscale to be eliminated. This feature is particularly valuable for low distortion reconstructions of low amplitude signals. Output glitch is also small, contributing to the overall high level of performance. The output amplifier achieves fast settling and high slew rates, providing a full ±3 V signal at load currents of up to ±8 mA.
