PRODUCTION DATA.
Do not leave the inputs of the AMC1106 unconnected (floating) when the device is powered up. If both modulator inputs are left floating, the input bias current drives these inputs to the output common-mode voltage level of the differential amplifier of approximately 1.9 V. If that voltage is above the specified input common-mode range, the gain of the differential amplifier diminishes and the modulator outputs a bitstream resembling a zero differential input voltage.
