ISLA112P50-55210EV1Z Daughter Board

Ultra Low Power Broadband 8 to 14-Bit Data Acquisition Platform


Quickly evaluate the amplifier, filter, & analog-to-ditial converter (ADC) signal chain's total performance in your application. Mating to Intersil's ADC KMB-001LEVALZ motherboard, this amplifier + ADC daughterboard provides a 100kHz to 100Mhz flat data acquisition channel requiring only 200mVpp (-10dBm) full scale input signal. It interfaces directly with Intersil's 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 Intersil ADC family. These low power ADC's span the 8- to 14-bit range with max sample rates from 125MSPS to 500MSPS.
