LTC1197/LTC1197L
LTC1199/LTC1199L
CO VERTER A D ULTIPLEXER CHARACTERISTICS
The q denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C.
VCC = 2.7V, VREF = 2.5V (LTC1197L), fCLK = fCLK(MAX) as defined in Recommended Operating Conditions, unless otherwise noted.
