DC393A, Demo Board Digitally Programmable Amplifier and Filter

DC393A, Demonstration circuit allows the user to evaluate the LTC1564 digitally controlled antialiasing filter. The cutoff frequency (fC) and passband gain are fully programmable while the shape of the low pass response is fixed. A latching digital interface stores fC and gain settings or it can be bypassed for control directly from the pins through either the on-board toggle switches or using the optional connector to control the pins externally
