7.3.3 Analog Output

The AMC0x30S-Q1 provides a single-ended analog output voltage that is 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 mid-range 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:

Equation 1. VOUT = VIN + VREFIN = (VINP – VSNSN) + VREFIN

The device is linear within the specified linear fullscale range. Beyond the linear fullscale 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 7-2 shows the input-to-output transfer characteristic.
