8-Bit, 120MSPS, Flash A/D Converter
The HI3246 is an 8-bit, high-speed, flash analog-to-digital
converter optimized for high speed, low power, and ease of
use. With a 120MSPS encode rate capability and full-power
analog bandwidth of 200MHz, 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 HI3246 clock input interfaces
directly to TTL, ECL or PECL logic and will operate with single-
ended inputs. The user may select 16-bit demultiplexed output
or 8-bit single channel digital outputs. The demultiplexed mode
interleaves the data through two 8-bit channels at ¹/₂ the clock
rate. Operation in demultiplexed mode reduces the speed and
cost of external digital interfaces, while allowing the A/D
converter to be clocked to the full 120MSPS conversion rate.
Fabricated with an advanced Bipolar process, the HI3246 is
provided in a space-saving 48-lead MQFP surface mount
plastic package and is specified over the -20^oC to 75^oC
temperature range.
