TYPICAL CHARACTERISTICS (continued)
All parameters are specified at T
A
= +25°C with V
CC
= +5V, V
DD
= +3.3V, and a measurement bandwidth from 10Hz to 20kHz, unless otherwise
noted. System clock frequency is equal to 256f
S
for Single and Dual Rate sampling modes, and 128f
S
for Quad Rate sampling mode.
