AD1851RZ-REEL7

AD1851 is a 16bit monolithic PCM audio DAC. Each device provides a voltage output amplifier, DAC, serial-to-parallel register and voltage reference. The digital portion of the AD1851 is fabricated with CMOS logic elements that are provided by Analog Devices’ 2µm ABCMOS process. The analogue portion of the AD1851 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 play-back. Laser-trimming of the linearity error affords 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 reproductions of low amplitude signals. Typical application includes high-end compact disc players, digital audio amplifiers, DAT recorders and players synthesizers and keyboards.
