This manual assists users in using the ADS5525/27/45/46/47 evaluation module (EVM) for evaluating the
performance of the ADS5525/27/45/46/47 (ADCs). The EVM provides a powerful and robust capability in
evaluation of the many features of the ADCs and the performance of the device der many conditions.
Analog input to the ADC is provided via external SMA connectors. The user supplies a single-ended input,
which is converted into a differential signal. One input path uses a differential amplifier, while the other
input is transformer-coupled.
The EVM provides an external SMA connector for input of the ADC clock. The single-ended input is
converted into a differential signal at the input of the device.
Digital output from the EVM is via a 40-pin connector.
Power connections to the EVM are via banana jack sockets. Separate sockets are provided for the ADC
analog and digital supplies, the FPGA supply, and the differential amplifier supply.
CAUTION
Exceeding the maximum input voltages can damage EVM components.
Undervoltage may cause improper operation of some or all of the EVM
components.
