Description

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 one hundred 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 pack- ages and are compliant to MIL-STD-883 Class B. The AD9012 is available in versions compliant with MIL-STD- 883. Refer to the Analog Devices Military Products Databook or current AD9012/883B data sheet for detailed specifications.
