AD1891JN Overview
In the 28-DIP (0.600, 15.24mm) package, the encoder is embedded.When packing the encoder, it is recommended to use a Tube case.There is a Through Hole-axis mount for this motor encoder.Sample Rate Converter is a classification for the type.Mixing, Routers-connected encoders are suitable for it.The optical encoder provides switching power through its 2.7V~5.5V digital power.The optical encoder is available with 28 terminations.The rotary encoders has 28 pins in total.It is recommended that the minimum supply voltage be higher than 2.7V.At max supply voltage (Vsup), 5.5V is reached.It is important to keep in mind that this encoder should be used at temperatures up to 85°C.It is designed to operate at a minimum temperature of -40°C.These electrical quadrature encodes can be found in the SamplePort™ series.
