Note 12: The input voltage range for the analog inputs is with respect to the voltage on the negative input of its respective differen-
tial or pseudo-differential pair. Table 5 shows which inputs form differential pairs.
Note 13: VREF = VREFIN+ - VREFIN-.
Note 14: These specifications apply to CLKOUT only when driving a single CMOS load.
Note 15: The burn-out currents require a 500mV overhead between the analog input voltage and both V+ and AGND to operate cor-
rectly.
Note 16: Measured at DC in the selected passband. PSR at 50Hz will exceed 120dB with filter notches of 25Hz or 50Hz and FAST
bit = 0. PSR at 60Hz will exceed 120dB with filter notches of 20Hz or 60Hz and FAST bit = 0.
Note 17: PSR depends on gain. For a gain of +1V/V, PSR is 70dB typical. For a gain of +2V/V, PSR is 75dB typical. For a gain of
+4V/V, PSR is 80dB typical. For gains of +8V/V to +128V/V, PSR is 85dB typical.
Note 18: Standby power-dissipation and current specifications are valid only with CLKIN driven by an external clock and with the
external clock stopped. If the clock continues to run in standby mode, the power dissipation will be considerably higher.
