Principal components are Precision Monolithics CMP-11CJ voltage comparator, SMP81FY sample-and-hold amplifier, SN74LS136N open-collector EXCLUSIVE-OR gate package, and DG201 quad analog switch DC accuracy is within 5 mV at zero scale and within 10 mV at full scale. Resistors and diodes provide input overvoltage protection for comparator. Comparator continuously examines difference between analog input voltage and voltage peak held by sample-and-hold amplifier, If input exceeds held value, new input is held.-D.
