ET9570LH Datasheet (IC Haus) - 3-Ch. Diff. Amplifier-comparator

ET9570LH, 3-Ch. Diff. Amplifier-comparator

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,
