ET9560
DESCRIPTION
These devices are specifically designed as receiver circuits for the photodiode signals available in optical encoders.
Connect the anode of the photodiodes to the input pins, with the cathode(s) connected to Vcc for reverse-bias
operation. The input amplifiers have a dynamic range of nearly 1000:1, and allow contrast ratios of encoded signal to
common mode signal of as low as 2:1. Differential inputs enhance noise rejection and performance over temperature.
Gating of the Z channel provides synchronization of the reference pulse to the data channel phasing.
