HI3286

Data Sheet June 1999

8-Bit, 160MSPS, Flash A/D Converter

The HI3286 is an 8-bit, high-speed, flash analog-to-digital
converter optimized for high speed, low po wer, and ease of
use. With a 160MSPS encode rate capability and full-power
analog bandwidth of 250MHz, this component is ideal for
applications requiring the highest possible dynamic
performance.

To minimize system cost and power dissipation, only a +5V
power supply is required. The HI3286 clock input interfaces
directly to TTL, ECL or PECL logic and will operate with single­ended inputs. The user may select 16-bit demultiple xed output
or 8-bit single channel digital outputs. The demultiplex ed mode
interleaves the data through two 8-bit channels at

1

/2 the clock
rate. Operation in demultiple x ed mode reduces the speed and
cost of external digital interfaces, while allowing the A/D
converter to be clocked to the full 160MSPS conv ersion r ate .

Fabricated with an advanced Bipolar process, the HI3286 is
provided in a space-saving 48-lead LQFP surface mount
plastic package and is specified over the -20

o

C to 75oC

temperature range.
