Note 16: These specifications apply to CLKOUT only when driving a single CMOS load.
Note 17: The burn-out currents require a 500mV overhead between the analog input voltage and both V+ and AGND to operate
correctly.
Note 18: 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 19: 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 20: 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.
When used with a resonator or crystal between CLKIN and CLKOUT, the actual power dissipation and IDD in standby
mode will depend on the resonator or crystal type.
