... NPC SM5805 digital decimation fil- ter used in consumer audio products. The AD1876 is also compatible with a variety of DSP processors. The AD1876 is packaged in a space saving 16-pin plastic DIP and operates from +5 V and 12 V supplies; typical power con- sumption is 235 mW. The digital supply (V ...

... ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AD1876 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality ...

... IMD products are normalized input signal. APERTURE DELAY Aperture delay is the time required after SAMPLE is taken LOW for the internal sample-hold of the AD1876 to open, thus holding the value of V APERTURE JITTER Aperture jitter is the variation in the aperture delay from sample to sample. – ...

... Sample-Hold Amplifier and initiates conversion (see “Conversion Control” paragraph). Dur- ing calibration, SAMPLE is active HIGH, forcing D during calibration CLK DI Master Clock Input. The AD1876 requires 17 clock pulses to execute a conversion. CLK is also used to derive Serial Output Data, Twos Complement format. ...

... RAM are then used during subsequent conversions to adjust conversion results. As shown in Figure 1, when CAL is taken HIGH the AD1876 internal circuitry is reset, the BUSY pin is driven HIGH and the part prepares for calibration. This is a ‘hard’ reset and will inter- rupt any conversion or calibration currently in progress ...

... AD1876 is to connect one or more AD1876s to an NPC SM5805 digital filter. This device supplies all signals required to operate the AD1876 kHz sample rate, which audio applications. This is more fully discussed in the applications section of this data sheet, accompanied by Figures 9 and 10. ...

... AD1876 VOLTAGE REFERENCE The AD1876 requires the use of an external voltage reference. The input voltage range is determined by the value of the refer- ence voltage; in general, a reference voltage of n volts produces an input range of n volts. Signal-to-noise performance is in- creased proportionately with input signal range. The AD1876 is specified with a 5 ...

... However, wideband noise contributed by the 9 AGND SENSE AD1876 will not be reduced by the antialias filter. The AD1876 contributed noise is evenly distributed from dc to the Nyquist rate, and this fact can be used to minimize its overall effect. The AD1876 contributed noise effects can be reduced by oversampling— ...

... A simple method for generating the required signals for the AD1876 is to connect one or more AD1876s to an NPC SM5805 digital filter. This device supplies all signals required to operate the AD1876 kHz sample rate, which audio applications. To minimize group delay distortion, the input to the AD1876 is filtered only by a low order analog filter ...
