SWITCHING CHARACTERISTICS
((V
ply, R
Note 1: Associated output voltage may be determined by multiplying the input voltage by the specified gain (A
Note 2: Logic-level characteristics apply to the following pins: DIN, DOUT, SCLK, CE, UPDATE, RESET, A3–A0, MODE, and AOUT.
Note 3: Switching transient settling time is guaranteed by the settling time (t
Note 4: Input test signal: 3.58MHz sine wave of amplitude 40IRE superimposed on a linear ramp (0 to 100IRE). IRE is a unit of
