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

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.
