noted.) All specifications TMIN to TMAX unless otherwise noted.
5Sample tested at 25
°C to ensure compliance.
6The glitch impulse transferred to the output of one converter (not addressed) due to a
change in the digital input code to another addressed converter.
Specifications subject to change without notice.
