DESCRIPTION
The ET2010 ASP is a monolithic bipolar ASIC designed to transform nanoamp-level differential photocurrents into 1Vpp sinewaves that are suitable for interpolation. A gain adjustment is provided that affects all channels in concert. Separate balance adjustments are provided for each output, for centering the waveforms on the reference voltage. In applications where the photocurrents are generated in phased-array photodiodes, the balance adjustments are generally not needed. In these cases, the BAL pins should be connected to GND. In most encoder designs, the LED optical output level changes with...
