The flexibility of the design architecture and process delivers latch-up free operation without external components and operation over the full military range. The ADC-208A is mechanically and electri- cally equivalent to the ADC-208 Series, with the exception of the OVERFLOW (pin 13) and ENABLE (pins 11 and 12) functions. These functions are not offered on the ADC-208A.
