ELECTRICAL CHARACTERISTICS

PCM4104-EP

SBAS419 – JUNE 2007

All parameters are specified at TA = 25°C with VCC = 5 V, VDD = 3.3 V, (unless otherwise noted) and a measurement

bandwidth from 10 Hz to 20 kHz, unless otherwise noted. System clock frequency is equal to 256fS for Single and Dual Rate

sampling modes, and 128fS for Quad Rate sampling mode.
