CS42L73
ABSOLUTE MAXIMUM RATINGS
Test Conditions: GND = AGND = PGND = CPGND = DGND = 0 V; all voltages are with respect to ground (GND).
WARNING: Operation at or beyond these limits may result in permanent damage to the device. Normal operation
is not guaranteed at these extremes.
Notes:
4. VP must be applied before VA is applied. VP must be removed after VA is removed.
5. Any pin except supplies. Transient currents of up to ±100 mA on the analog input pins will not cause SCR latch-up.
6. The maximum over/under voltage is limited by the input current.
7. • V
FLT-x
is the applied voltage that causes a contention fault condition between its source and the CS42L73 output.
• ±VCPFILT are specified in “DC Electrical Characteristics” on page 21.
• The specification applies to both the signal and pseudodifferential reference pins, where applicable.
