DESCRIPTION
The ADC614 is a high dynamic range analog-to-
digital converter capable of digitizing signals at any
rate from DC to 5.12 megasamples per second. Out-
standing spurious-free dynamic range has been
achieved by minimizing potential distortion sources.
The ADC614 is a two-step subranging ADC sub-
system containing an ADC, sample/hold amplifier,
voltage reference, timing, and error-correction cir-
cuitry in a 46-pin hybrid DIP package. The
logic interface is TTL. An evaluation board
(DEM-ADC614-E) is available for quick evaluation.
