8-Bit, 750Msps Flash ADC
_______________General Description
The MAX1151 is a parallel flash analog-to-digital con-
verter (ADC) capable of digitizing full-scale (0V to -2V)
inputs into 8-bit digital words at an update rate of
750Msps. The ECL-compatible outputs are demuxed
into two separate output banks, each with differential
data-ready outputs to ease the task of data capture.
The MAX1151’s wide input bandwidth and low capaci-
tance eliminate the need for external track/hold amplifi-
ers for most applications. A proprietary decoding
scheme reduces metastable errors to 1LSB. This device
operates from a single -5.2V supply, with a nominal
power dissipation of 5.5W.
