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 supply voltage, temperature, and age. This
causes corresponding changes in the photocurrent signal levels. The ASP rejects these variations in the input
signals, resulting in output levels that are stable over time, temperature, and supply voltage. In practice, the
maximum usable gain setting may be limited by noise considerations. The comparators in Interpolation ASIC's
have a minimal amount of hysteresis, and care must be taken that the noise is well below the hysteresis value. If
necessary, the noise can be reduced by lowering the photodiode capacitance or by rolling off the ASP outputs with
RC filters.
