... The MAX9813 has two inputs allowing two microphones to be multiplexed to a single output. The MAX9812/MAX9813 are offered in two grades. The MAX9812L/MAX9813L are optimized for 3.3V supply operation (2.7V to 3.6V). The MAX9812H/MAX9813H are PC2001 compliant and are optimized for 5V operation (4.5V to 5.5V). Both devices are specified over the -40° ...

... 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. ELECTRICAL CHARACTERISTICS (V = 3.3V 500µA (MAX9812L/MAX9813L BIAS SHDN = unless otherwise noted ...

... Amplifer Input 1 (MAX9813) Amplifier Input 2 (MAX9813) Input Selector. When IN1/IN2 is high, IN1 is selected. When IN1/IN2 low, IN2 is selected. The output DC bias point is set to 1.5V for the MAX9812L/ MAX9813L and 2.5V for the MAX9812H/MAX9813H. SHDN controls whether the MAX9812_/MAX9813_ is active or in shutdown mode. Driving SHDN low forces a low-power (100nA) shutdown mode ...
