with Equalization and Extended
Temperature Operation
Absolute Maximum Ratings
(Voltages referenced to GND.)
VCC........................................................................-0.3V to +4.0V
All Other Pins (Note 1).............................. -0.3V to (VCC + 0.3V)

OUT_P, OUT_M............................................................±30mA
Peak Current IN_P, IN_M, OUT_P, OUT_M
(pulsed for 1µs, 1% duty cycle)...................................±100mA
Continuous Power Dissipation (TA = +70°C)
TQFN (derate 35.7mW/°C above +70°C)..................2857mW
Operating Temperature Range............................ -40°C to +85°C
Junction Temperature Range............................ -40°C to +150°C
Storage Temperature Range............................. -65°C to +150°C

Soldering Temperature (reflow)........................................+260°C
Note 1: All I/O pins are clamped by internal diodes.
Stresses beyond those listed under âAbsolute Maximum Ratingsâ 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.
Package Thermal Characteristics (Note 2)
TQFN
Junction-to-Ambient Thermal Resistance (BJA).......... 28NC/W
Junction-to-Case Thermal Resistance (BJC)..................2NC/W
Note 2: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer
board. For detailed information on package thermal considerations, refer to www.maximintegrated.com/thermal-tutorial.
Electrical Characteristics
(VCC = +3.0V to +3.6V, CCL = 200nF coupling capacitor on each output, RL = 50Ω on each output, TA = -40°C to +85°C, unless otherwise
noted. Typical values are at VCC = +3.3V and TA = +25°C.) (Note 3)
