... ICs have symmetrical differential inputs and a single-ended output. They operate from ±5V supplies and are capable of driving a 100Ω load to ±3.7V. The MAX4444 has an internally set closed-loop gain of +2V/V, while the MAX4445 is compensated for gains of +2V/V or greater, set by an external resistor. A low-power enable mode reduces current consumption to 3 ...

... Ensure that the ground plane is free from voids. Low-Power Enable Mode The MAX4444/MAX4445 are disabled when EN goes low. This reduces supply current to only 3.5mA. As the output becomes higher impedance, the effective impedance at the output for the MAX4444 is 1.8kΩ. The effective output impedance for the MAX4445 is 1.8kΩ plus R . GAIN Maxim cannot assume responsibility for use of any circuitry other than circuitry entirely embodied in a Maxim product ...
