General description

The ADC0806030/040/050 are a family of 8-bit high-speed, low-power Analog-to-Digital Converters (ADC) for professional video and other applications. It converts the analog input signal into 8-bit binary coded digital signals 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 can also be used.

Features

■ 8-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 (7.8 effective bits at 4.43 MHz full-scale input at fclk = 40 MHz)

■ No missing codes guaranteed

■ In-Range (IR) CMOS output

■ TTL and CMOS levels compatible digital inputs

■ 3 V to 5 V CMOS digital outputs

■ Low-level AC clock input signal allowed

■ External reference voltage regulator

■ Power dissipation only 175 mW (typical)

■ Low analog input capacitance, no buffer amplifier required

■ No sample-and-hold circuit required

Applications

■ Video data digitizing

■ Radar

■ Transient signal analysis

■ Σ? modulators

■ Medical imaging

■ Barcode scanner

■ Global Positioning System (GPS) receiver
