GENERAL DESCRIPTION
EM19101 is a 8-bit CMOS A/D converter for scanner use. The adoption of a 2-step parallel system achieves low consumption at a maximum conversion speed of 7 MSPS.
FEATURES
7MSPS maximum conversion speed Build-in sampling and hold circuit Internal self-bias reference voltage 45 mW very low power dissipation at 5MSPS +5V single power supply Available in 24 pin SOP Series EM19101M for 300 mil SOP EM19101S for 209 mil SOP
APPLICATION
Scanner and a wide range of fields where high speed A/D conversion is required in the digital communication.
