ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICS
(VDD = PVDD = 5.0V, VGND = VPGND = VMUTE = 0V, VSHDN = 5V, RIN = RF = 15kΩ, RL = ∞. TA = TMIN to TMAX, unless otherwise
noted. Typical values are at TA = +25°C.) (Note 1)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
Note 1: All devices are 100% production tested at +25°C. All temperature limits are guaranteed by design.
Note 2: PSSR is specified with the amplifier inputs connected to GND through RIN and CIN.

PVDD to VDD .......................................................................±0.3V
PGND to GND.....................................................................±0.3V
All Other Pins to GND.................................-0.3V to (VDD + 0.3V)
Continuous Input Current (into any pin
except power supply and output pins).........................±20mA
Continuous Power Dissipation (TA = +70°C)
