... Die Thickness: The standard thickness of Analog Devices Bipolar dice is 24 mils Die Dimensions: The dimensions given have a tolerance of 2 mils. Backing: The standard backside surface is silicon (not plated). Analog Devices does not recommend gold-backed dice for most applications. Edges: A diamond saw is used to separate wafers into dice thus providing perpendicular edges half- way through the die ...

AD587 THEORY OF OPERATION The AD587 consists of a proprietary buried Zener diode refer- ence, an amplifier to buffer the output and several high stability thin-film resistors as shown in the block diagram in Figure 1. This design results in ...
