Description
The HI3086 is a 6-bit, high-speed, flash analog-to-digital con-
verter optimized for high speed, low power, and ease of use.
With a 140 MSPS 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 HI3086’s 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 140 MSPS conversion rate.
Fabricated with an advanced bipolar process, the HI3086 is
provided in a space-saving 48-lead MQFP surface mount
plastic package and is specified over the -20
o
C to 75
o
C
temperature range.
