General description The ADC1002S020 is a 10-bit high-speed Analog-to-Digital Converter (ADC) for professional video and other applications. It converts with 3.0 V to 5.25 V operation the analog input signal into 10-bit binary-coded digital words at a maximum sampling rate of 20 MHz. All digital inputs and outputs are CMOS compatible. A standby mode allows a reduction of the device power consumption to 4 mW. 2. Features I 10-bit resolution I 3.0 V to 5.25 V operation I Sampling rate up to 20 MHz I DC sampling allowed I High signal-to-noise ratio over a large analog input frequency range (9.3 effective bits at 1.0 MHz; full-scale input at fclk = 20 MHz) I In-Range (IR) CMOS output I CMOS/Transistor-Transistor Logic (TTL) compatible digital inputs and outputs I External reference voltage regulator I Power dissipation only 53 mW (typical value) I Low analog input capacitance, no buffer ampliﬁer required I Standby mode I No sample-and-hold circuit required 3. Applications I Video data digitizing I Camera I Camcorder I Radio communication I Barcode scanner 1 page NXP Semiconductors ADC1002S020 www.DataSheet4U.com Single 10 bits ADC, up to 20 MHz Table 3.
