FEATURES

GENERAL DESCRIPTION

The ADC-208A utilizes an advanced VLSI 1.2 micron CMOS

in providing 20MHz sampling rates at 8-bits. The ﬂ exibility

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 electrically 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.
