General description
The ADC1003S030/040/050 are a family of 10-bit high-speed low-power Analog-to-Digital Converters (ADC) for professional video and other applications. They convert the analog input signal into 10-bit binary-coded digital words at a maximum sampling rate of 50 MHz. All digital inputs and outputs are Transistor-Transistor Logic (TTL) and CMOS compatible, although a low-level sine wave clock input signal is allowed.

Features
■ 10-bit resolution
■ Sampling rate up to 50 MHz
■ DC sampling allowed
■ One clock cycle conversion only
■ High signal-to-noise ratio over a large analog input frequency range (9.3 effective bits at 4.43 MHz full-scale input at fclk = 40 MHz)
■ No missing codes guaranteed
■ In-Range (IR) CMOS output
■ Levels TTL and CMOS compatible digital inputs
■ 3 V to 5 V CMOS digital outputs
■ Low-level AC clock input signal allowed
■ Internal reference voltage regulator
■ Power dissipation only 235 mW (typical)
■ Low analog input capacitance, no buffer amplifier required
■ No sample-and-hold circuit required

Applications
High-speed analog-to-digital conversion for:
■ Video data digitizing
■ Radar
■ Transient signal analysis
■ Global Positioning System (GPS) receiver
■ Σ∆ modulators
■ Cellular based stations
■ Barcode scanner
■ Medical imaging
