PRODUCTION DATA
The AMC0100R provides a single-ended analog output voltage proportional to the input voltage. The output is referred to GND2 and is galvanically isolated from the input of the device. The output is designed to connect directly to the input of an ADC.
The full-scale output voltage is set by the REFIN pin. For any input voltage within the specified linear input range, the device outputs a voltage equal to:
Connect REFIN to the same reference voltage as a downstream ADC to match the ADC dynamic input voltage range. With a shared reference voltage, the ADC outputs a negative full-scale code when the negative clipping voltage is applied to the input of the AMC0100R. The ADC outputs the mid-range code when 0V is applied to the input of the AMC0100R. The ADC outputs a positive full-scale code when the positive clipping voltage is applied to the input of the AMC0100R.
The device is linear within the specified linear full-scale range. Beyond the linear full-scale range, the output continues to follow the input, but with reduced linearity performance. The output clips when the input voltage reaches the clipping voltage. Figure 6-2 shows the input-to-output transfer characteristic.
