The AD9012 is an 8-bit, ultrahigh speed, analog-to-digital
converter. The AD9012 is fabricated in an advanced bipolar
process that allows operation at sampling rates up to 100
megasamples/second. Functionally, the AD9012 is comprised
of 256 parallel comparator stages whose outputs are decoded
to drive the TTL compatible output latches.
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

offered in an industrial grade, –25°C to +85°C, packaged in a
28-lead DIP and a 28-lead JLCC. The military temperature
range devices, –55°C to +125°C, are available in ceramic DIP
and LCC packages and are compliant to MIL-STD-883 Class B.
The AD9012 is available in versions compliant with MIL-STD-883.
