8-BIT 5 M8S-BPIST 5AM/DSPCS OA/NDVCOENRVTEERRTE(RC(MCMOOSS))
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.
