ET9570 - 3-CHANNEL DIFFERENTIAL AMPLIFIER COMPARATOR

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.

Features

  • Supply Voltage Range 4.5V to 30V.
  • Operation to 1MHz.
  • Designed for photodiode inputs.
  • Index gated by A and B channels.
  • Current sink for LED drive (see.
