• Camera
• Camcorder
• Radio communication.
GENERAL DESCRIPTION
The TDA8766 is a 10-bit high-speed analog-to-digital
converter (ADC) for professional video and other
applications. It converts with 2.7 to 5.25 V operation the
analog input signal into 10-bit binary-coded digital words at
a maximum sampling rate of 20 MHz. All digital inputs and
outputs are CMOS compatible. A standby mode allows
reduction of the device power consumption down to 4 mW.
