Philips Semiconductors Product specification

10-bit high-speed low-power ADC 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 f

clk

= 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.
