Device Operation
Once the analog and digital power sources are applied to the AMC1203EVM, the digital outputs become
active. The AMC1203 is configured to use its onboard modulator clock. The internal reference of the
AMC1203 is used as the conversion reference.
active. The AMC1203 is configured to use its onboard modulator clock. The internal reference of the
AMC1203 is used as the conversion reference.
Additionally, an analog input signal may be applied directly at screw terminal J1. See
and
for more details. The analog input range, (VIN+) – (VIN–), is ±320 mV.
As the input voltage approaches the maximum input level of +320mV, the 1s density of the modulator
output approaches 92%. Likewise, when the input voltage approaches the lower limit of –320 mV, the 1s
density is approximately 8%.
