Analog Devices Inc. ADA4356 Current-to-Bits Receiver µModule is a low-noise, wide dynamic-range, current input, analog-to-digital converter (ADC) µModule. For space savings in size-conscious applications, the ADA4356 includes all the required active and passive components to realize a complete current-to-bits data-acquisition solution with programmable gain and filter characteristics. The high-speed transimpedance amplifier (TIA) front-end amplifier in the ADA4356 supports 20ns pulse widths, which allows high spatial resolution for Time of Flight (ToF) measurements, and exhibits fast overdrive recovery from large input signals. The ADA4356 includes three selectable TIA feedback resistor values for programmable TIA gain. An internal analog low-pass filter offers either 100MHz or 1MHz cutoff frequencies to reduce broadband noise and serve as an anti-aliasing filter for the ADC inputs. For lower bandwidth signals, the 1MHz filter configuration offers additional noise reduction.
