Product speciﬁcation

10-bit high-speed low-power ADC

TDA8764A

FEATURES

• 10-bit resolution (binary or gray code)

• Sampling rate up to 60 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 5 MHz full-scale

input at fclk = 60 MHz)

• No missing codes guaranteed

• In Range (IR) CMOS output

• TTL and CMOS levels compatible digital inputs

• 2.7 to 3.6 V CMOS digital outputs

• Low-level AC clock input signal allowed

• Power dissipation only 312 mW

• 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

• High energy physics research

• Transient signal analysis

•Σ∆ modulators

• Medical imaging.

GENERAL DESCRIPTION

The TDA8764A 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 or gray coded digital words at a maximum

sampling rate of 60 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.
