Appendix B - Discrete Parts List

The following list of components shows the approximate number of various components in the discrete section of the electronics for the PHA.  The number shown is for one complete flight package.  Note there are several special items not found elsewhere in the experiment.  These include the reference zener, precision resistors, R/2R ladder network, and one special ±50 ppm/șC resistor.  Also a range of chip values needed for amplifier offset tailoring is shown.
