An input signal of 0V ideally produces a stream of ones and zeros that are high 50% of the time. An input of 1V (VSNSP – VSNSN) produces a stream of ones and zeros. This stream is high 90% of the time. With 16 bits of resolution, that percentage ideally corresponds to code 58982. An input of –1V produces a stream of ones and zeros that are high 10% of the time. With 16 bits of resolution, that percentage ideally corresponds to code 6554. These input voltages are also the specified linear range of the AMC0386-Q1. If the input voltage value exceeds this range, the output of the modulator shows increasing nonlinear behavior as the quantization noise increases. The modulator output clips with a constant stream of zeros at an input ≤–1.25V. The modulator output also clips with a constant stream of ones at an input ≥1.25V. In this case, however, the AMC0386-Q1 generates a single 1 or 0 every 128 clock cycles to indicate proper device function. A single 1 is generated if the input is at negative full-scale and a 0 is generated if the input is at positive full scale. See the Output Behavior in Case of a Full-Scale Input section for more details. Figure 7-4 shows the input voltage versus the output modulator signal.
The following equation calculates the density of ones in the output bitstream for any input voltage VIN = (VSNSP – VSNSN) value. The only exception is a full-scale input signal. See the Output Behavior in Case of a Full-Scale Input section.
