The exceptionally wide large-signal analog input bandwidth of 160 MHz is due to an innovative comparator design and very close attention to device layout considerations. The wide input bandwidth of the AD9012 allows very accurate acquisition of high speed pulse inputs without an external track-and-hold. The comparator output decoding scheme minimizes false codes, which is critical to high speed linearity. The AD9012 is available in two grades: one with 0.5 LSB linearity and one with 0.75 LSB linearity. Both versions are
