TDA8760
FEATURES
• 10-bit resolution
• Sampling rate up to 40 MHz
• Total Harmonic Distortion (THD): −65 dB at 4.43 MHz
full-scale and a 40 MHz clock frequency
• High signal-to-noise ratio over a large analog input
frequency range (8.8 effective bits at 10 MHz full-scale
input at a 40 MHz clock frequency)
• +5 V power supplies
• Binary or two’s complement 3-state TTL outputs
• In-range 3-state TTL output
• TTL compatible digital inputs
• LOW-level AC clock input signal allowed
• Power dissipation 850 mW (typical)
• Low analog input capacitance (typ. 4.5 pF), no buffer
amplifier required
• No external sample-and-hold circuit required
• Analog Input; single or differential
• External amplitude range control
• Voltage controlled regulator included.
APPLICATIONS
• High-speed analog-to-digital conversion for
– Video signal digitizing
– High Definition TV (HDTV)
– Digital video broadcasting (satellite and cable)
– Transient signal analysis
– High energy physics research
– Sigma-delta (SD) modulators
– Medical imaging
– Radar pulse digitizing.
GENERAL DESCRIPTION
The TDA8760 is a monolithic bipolar 10-bit
Analog-to-Digital Converter (ADC) for video or other
applications. It converts the analog input signal into 10-bit
binary coded digital words at a maximum sampling rate of
40 MHz. All digital inputs and outputs are TTL compatible.
However, a sine wave clock input signal is allowed.

LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).
HANDLING
Inputs and outputs are protected against electrostatic discharges in normal handling. However, to be totally safe, it is
desirable to take normal precautions appropriate to handling integrated circuits.
