The device with speeds up to 150 MSPS. Encapsulated in a 6 mm 12 mm integrates all active and passive components to form a complete CSP BGA package, the ADAQ8088 minimizes space signal chain between the output of an I/Q demodulator and the requirements in high density multichannel systems. input to an analog-to-digital converter (ADC). The device also The ADAQ8088 operating temperature range is from 40C forms the complete signal chain between a transducer output to +85C. and the input to an ADC in baseband data acquisition systems. No external components are required for proper functionality. Rev. 0 Document Feedback Information furnished by Analog Devices is believed to be accurate and reliable.
