TYPICAL CHARACTERISTICS (continued)

All parameters are specified at TA = +25°C with VCC = +5V, VDD = +3.3V, and a measurement bandwidth from 10Hz to 20kHz, unless otherwise

noted. System clock frequency is equal to 256fS for Single and Dual Rate sampling modes, and 128fS for Quad Rate sampling mode.
