Description
The HI3026 is an 8-bit, high-speed, flash analog-to-digital
converter optimized for high speed, low power, and ease of
use. With a 120 MSPS encode rate capability and full-power
analog bandwidth of 150MHz, this component is ideal for appli-
cations requiring the highest possible dynamic performance.
To minimize system cost and power dissipation, only a +5V
power supply is required. The HI3026’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 con-
verter to be clocked to the full 120 MSPS conversion rate.
Fabricated with an advanced Bipolar process, the HI3026 is
provided in a space-saving 48-lead MQFP surface mount
plastic package and is specified over the -20°C to 75°C
temperature range. For a faster clock rate, please refer to
the HI3026A (140 MSPS).
