Electrical Characteristics
DC PARAMETER: CONVERTER CHARACTERISTICS
(The following conditions apply to all the following parameters, unless otherwise specified.)
DC:
VA+ = VD+ = 5V, Vref+ = 5V, Vref- = 0V, Rs = 25 Ohms, 12-bit+sign conversion mode fCLK = 8.0MHz, source
impedance for Vref+ and Vref- <25 Ohms, fully-differential input with fixed 2.5V common-mode voltage,
and minimum acquisition time.
