... Input impedances in the megaohm range on both the signal and gain control inputs simplify driving the CLC5523 in any application. The CLC5523 can be configured to use pin low impedance input making it an ideal interface for current inputs. By using the CLC5523’s inverting configuration in which R is driven directly, inputs which exceed the device’ ...

... Broad signal and gain control bandwidths Frequency response may be adjusted with R High Impedance signal and gain control Inputs The CLC5523 combines a closed loop input buffer, a volt- age controlled variable gain cell and an output amplifier. The input buffer is a transconductance stage whose gain ...

... For example, with 46dB of gain, a 20mV signal at the input will drive the out- put of the CLC425 to 200mV, the output of the CLC5523 to 4V. Accordingly, the designer must carefully consider the contributions of each stage to the overall characteris- tics ...
