 MICROCONTROLLERS AND PCB DESIGN
This page shows some examples of our capabilities
BST0051A
BST0050A
WITH
20 BITS A/D MEZZANINE
 {short description of image} Microcontroller Data Logger.
Shown in the picture:
BST0050A and the BST0051A in conjunction with a custom made 20 bits A/D. This arrangement is used to control the deposit of CADMIUM on steel plates by detecting the weight loss on the Cadmium ingots. In addition to the weight detection, a second A/D channel is used to control the bath temperature while a third A/D channel monitors the anodizing current and in conjunction with the PWM is used to regulate the plating bath current. The A/D board has a DC/DC converter to generate the voltage necessary to excite the load cell.
