Description
The CXD1175A is an 8-bit CMOS A/D converter
for video use. The adoption of a 2-step parallel
system achieves low consumption at a maximum
conversion speed of 20MSPS minimum, 35MSPS
typical.
Features
Resolution: 8 bit ± 1/2LSB (DL)
Maximum sampling frequency: 20MSPS
Low power consumption: 60mW (at 20MSPS typ.)
(reference current excluded)
Built-in sampling and hold circuit
Built-in reference voltage self-bias circuit
3-state TTL compatible output
Power supply: 5V single
Low input capacitance: 11pF
Reference impedance: 300
(typ.)
Applications
TV, VCR digital systems and a wide range of fields
where high speed A/D conversion is required.
