LSI/CSI
LSI/CSI

To supplement our line of motors and encoders, Anaheim Automation is introducing a line of Integrated Circuit (IC) chips. Our IC chips are ideal for high volume, high performance chips at a low cost, which is a great solution for any OEM. The IC chips are 100% tested and guaranteed using advanced ATE. These IC chips are readily available in stock and ready to ship. Anaheim Automation offers IC chips for the following products: Incremental Encoder Interface, Brushless DC Motor Control, Stepper Motor Control, and AC Motor Control. There is a 10 piece minimum order on our LSI/CSI IC Chips.
