4 / 20 page TEMPERATURE RANGE Min Typ Max Unit Specifications Guaranteed 25 °C Functionality Guaranteed –40 +85 °C Storage –60 +100 °C DIGITAL FILTER CHARACTERISTICS Min Typ Max Unit Decimation Factor 64 Passband Ripple 0.006 dB Stop Band 1 Attenuation 90 dB 48 kHz fS (at Recommended Crystal Frequencies) Passband 0 21.6 kHz Stop Band 26.4 kHz 44.1 kHz fS (at Recommended Crystal Frequencies) Passband 0 20 kHz Stop Band 24.25 kHz 32 kHz fS (at Recommended Crystal Frequencies) Passband 0 14.4 kHz Stop Band 17.6 kHz Other fS Passband 0 0.45 fS Stop Band 0.55 fS Group Delay 36/fS s Group Delay Variation 0 µs NOTES 1Stop band repeats itself at multiples of 64 × fS, where fS is the output word rate. Thus the digital filter will attenuate to 0 dB across the frequency spectrum except for a range ± 0.55 × fS wide at multiples of 64 × fS. Specifications subject to change without notice. ABSOLUTE MAXIMUM RATINGS Min Typ Max Unit DVDD1 to DGND1 and DVDD2 to DGND2 0 6 V AVDD to AGND/AGNDL/AGNDR 0 6 V Digital Inputs DGND – 0.3 DVDD + 0.3 V Analog Inputs AGND – 0.3 AVDD + 0.3 V AGND to DGND –0.3 +0.3 V Reference Voltage Indefinite Short Circuit to Ground Soldering (10 sec) 300 °C ORDERING GUIDE Package Package Model Temperature Description Option AD1870JR –40 °C to +85°C SOIC R-28 CAUTION 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 AD1870 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. WARNING! ESD SENSITIVE DEVICE AD1870–SPECIFICATIONS –4– REV. 0 |
