DC962A-C

DC962A-C is a demonstration circuit featuring LT6600-10 fully differential 4th order lowpass filter approximating a Chebyshev frequency response. The LT6600-XX combines a low pass filter with a fully differential amplifier for driving the differential input of an ADC. An LT6600-10 also provides the necessary level shifting to set its output common mode voltage to accommodate the reference voltage requirements of an ADC. An LT6600-10 filter IC requires only two external input resistors to set the filter’s differential gain. A DC962 board contains an LT6600-10 low pass filter configured with input resistors as a unity gain differential amplifier. Gains greater than one requires changing input resistors to a low er value. Connection to the differential I/P and O/P of DC962 is through SMA connectors. On-board jumpers configure the DC962 for dual or single supply operation.
