ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS—5V Supply

(VCC = 5V, GND = 0, SHDN = VCC, TA = +25°C. CBIAS = 1µF, RIN = RF = 20k

Ω (MAX9716/MAX9717A), IN+ = BIAS (MAX9716),

BTL/SE = GND (MAX9717_), RL =

∞ connected between OUT+ and OUT-. Typical values are at TA = +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.

Supply Voltage (VCC to GND) ..................................-0.3V to +6V

Any Other Pin to GND ...............................-0.3V to (VCC + 0.3V)

IN_, BIAS, SHDN, BTL/SE Continuous Current...................20mA

OUT_ Short-Circuit Duration to GND or VCC (Note 1)...Continuous

Continuous Power Dissipation (TA = +70°C)
