• Description: 8-bit 160MSPS Flash A/D Converter
• Manufacturer: Sony Corporation

2. Straight mode (See Application Circuits 1-(4), (5) and (6).)
Set the SELECT1 pin to GND for this mode. In this mode, data output can be obtained in accordance with the
clock frequency applied to the A/D converter for applications which use the clock applied to the A/D converter
as the system clock.
The A/D converter can operate at Fc (min.) = 125MSPS in this mode.
