ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICS—Single +5V Supply
(V+ = +5V ±5%, T
A
= T
MIN
to T
MAX
, unless otherwise noted. Typical values are at T
A
= +25°C.) (Note 2)
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.
V+ to GND................................................................-0.3V to +6V
NO_ _, S_, MID_, BYP, COM_ _, CBIASL,
ABIASL, CBIASH, ABIASH, DOUT to GND
(Note 1)......................................................-0.3V to (V+ + 0.3V)
CS, A0, A1, SDA, SCL, DIN,
SCLK to GND ........................................................-0.3V to +6V
Continuous Current into Any Terminal..............................±20mA
Peak Current, NO_ _, S_, COM_ _
(pulsed at 1ms, 10% duty cycle max)...........................±40mA
Continuous Power Dissipation (T
A
= +70°C)
36-Pin SSOP (derate 11.8mW/°C above +70°C) ..........941mW
Operating Temperature Range ............................-40°C to+85°C
Storage Temperature Range..............................-65°C to+150°C
Lead Temperature (soldering, 10sec).............................+300°C
Note 1: Signals on NO_ _, S_, or COM_ _ exceeding V+ or GND are clamped by internal diodes. Limit forward diode current to
maximum rating.
