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

■ 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
