FEATURES - - - - - - - Supply Voltage Range 4.5V to 30V Operation to 1MHz Designed for photodiode inputs Ungated Index channel Current sink for LED drive (see application note APP-D2) Outputs short circuit protected 25m A peak drive current APPLICATIONS - - High Speed Optical Encoders Industrial Controls 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 mon 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.
