GENERAL DESCRIPTION
The TDA8793 is an 8-bit low-power Analog-to-Digital
Converter (ADC) which includes a track-and-hold circuit
and internal references. The device converts an analog
input signal, up to 100 MHz, into 8-bit binary codes at a
maximum sample rate of 100 Msps. All digital inputs and
output are TTL/CMOS compatible. A sine wave clock input
signal can also by used.
The Power-down mode enables the device power
consumption to be reduced to 5 mW.
