One feedback (input) photodiode is used to generate a control signal that provides a servomechanism to the LED drive current, thus compensating for the LED’s nonlinear time and temperature characteristics. The other (output) photodiode provides an output signal that is linear to the servo LED current. The IC features wide bandwidth, high input-to-output isolation, and excellent servo linearity.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSupply input Side 5V DC\u003c\/li\u003e\n\u003cli\u003eSupply Output Side 5V DC\u003c\/li\u003e\n\u003cli\u003eInput Voltage Range 0-5V DC\u003c\/li\u003e\n\u003cli\u003eOutput 0-3.3V DC\u003c\/li\u003e\n\u003cli\u003ePCB Dimensions: 30.48 x 12.86 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eConnections\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePin 1 = VCC 5V DC, Pin 2 = Analog Input 0-5V DC, Pin 3 = GND Input Side\u003c\/li\u003e\n\u003cli\u003ePin 1 = VCC2 5V DC, Pin 2 = Analog Output 0-3.3V DC, Pin 3 GND Output Side\u003c\/li\u003e\n\u003cli\u003eD1 = Power LED Input Side\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"dotfry","offers":[{"title":"Default Title","offer_id":47223357800620,"sku":"D115","price":34.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/6436\/7532\/files\/D115.jpg?v=1789563517","url":"https:\/\/dotfry.com\/products\/isolated-analog-input-module-v2","provider":"dotfry","version":"1.0","type":"link"}
