GENERAL DESCRIPTION
EM19100 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 20 MSPS typical.
FEATURES
• 20MSPS maximum conversion speed
• Build-in sampling and hold circuit
• Internal self-bias reference voltage
• 90mW power dissipation at 20MSPS
• +5V single power supply
• Available in 24 pin SOP
• Series
EM19100M for 300 mil SOP
EM19100S for 209 mil SOP
APPLICATION
TV,VCR digital systems and a wide range of fields where high speed A/D conversion is required.
