DESCRIPTIONâ¦
The HS574A/SP674A Series are complete 12âbit successiveâapproximation A/D converters
integrated on a single die with tri-state output latches, an internal reference, clock and a sampleâ
hold. They feature 12âbit linearity over temperature, low power dissipation and fast conversion
time. They are available in commercial and military temperature ranges.
