TDA8763A

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 (9.4 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 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

High-speed analog-to-digital conversion for:

• Video data digitizing

• Radar pulse analysis

• Transient signal analysis

• High energy physics research

•Σ∆ modulators

• Medical imaging.

GENERAL DESCRIPTION

The TDA8763A is a 10-bit high-speed low-power

analog-to-digital converter (ADC) for professional video

and other applications. It converts 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

TTL and CMOS compatible, although a low-level sine

wave clock input signal is allowed.

The device requires an external source to drive its

reference ladder. If the application requires that the

reference is driven via internal sources the

recommendation is to use the TDA8763.
