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.
