... This overflow output can be disabled with the overflow inhibit pin. The AD9002 is available in two grades, one with 0.5 LSB lin- earity and one with 0.75 LSB linearity. Both versions are offered in an industrial grade, – +85 C, packaged in a 28-lead DIP and a 28-leaded JLCC. The military temperature range devices, – ...

... Dramatic improvements in comparator design and construction give the AD9002 excellent dynamic characteristics, especially SNR (signal-to-noise ratio). The 160 MHz input bandwidth and low error rate performance give the AD9002 an SNR with a 1.23 MHz input. High SNR performance is par- ticularly important in wide bandwidth applications, such as pulse signature analysis, commonly performed in advanced radar receivers ...
