EMEM1911910000
8-BIT 20 MS8-PBSITV20IDMESPOS AVI/DDECO OA/NDVCOENRVTEERRTE(RC(MCMOOSS))
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.

with the following rising edge. The delay from the clock rising edge to the data output is about 18ns.
OE pin
By connecting OE to GND output mode is obtained. By connecting to VDD high impedance is obtained.
About latch up
It is necessary that AVDD and DVDD pins be the common source of power supply. This is to avoid latch up
due to the voltage difference between AVDD and DVDD pins when power is ON.
