www.ti.com SNAS186B – APRIL 2003 – REVISED MARCH 2013 ADC12020 12-Bit, 20 MSPS, 185 mW A/D Converter with Internal Sample-and-Hold
Check for Samples: ADC12020 FEATURES DESCRIPTION The ADC12020 is a monolithic CMOS analog-todigital converter capable of converting analog input
signals into 12-bit digital words at 20 Megasamples
per second (MSPS), minimum. This converter uses a
differential, pipeline architecture with digital error
correction and an on-chip sample-and-hold circuit to
minimize die size and power consumption while
providing excellent dynamic performance. Operating
on a single 5V power supply, this device consumes
just 185 mW at 20 MSPS, including the reference
current. The Power Down feature reduces power
consumption to 40 mW. 1 23 Internal sample-and-hold
