Quickly evaluate the amplifier, filter and analog-to-digtal converter (ADC) signal chain's total performance in your application. Pairing with Renesas' ADC KMB-001LEVALZ motherboard, this amplifier + ADC daughterboard provides a 100kHz to 100MHz flat data acquisition channel requiring only 200mV p-p (-10dBm) full scale input signal. It interfaces directly with Renesas' proven ADC analysis Konverter software. Typically consuming <680mW in the amplifier + ADC, this example design also offers a starting point for customizing this board to specific end equipment requirements.
The input transformers, amplifier gain and interstage filter design can be tuned for a given application, allowing a user to try different circuit configurations to evaluate performance tradeoffs. In addition, the 12-bit 500MSPS ADC can be swapped out for any of the 20-pin compatible ADCs from the Renesas ADC family. These low power ADC's span the 8- to 14-bit range with max sample rates from 125MSPS to 500MSPS.
