8-Bit, 140 MSPS, Flash A/D Converter

Description

The HI3026A is an 8-bit, high-speed, flash analog-to-digital
converter optimized for high speed, low power, and ease of
use. With a 140 MSPS encode rate capability and full-power
analog bandwidth of 150MHz, 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 HI3026A’s clock input interfaces
directly to TTL, ECL, or PECL logic and will operate with single­ended 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
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 conv ersion r ate .

Fabricated with an advanced bipolar process, the HI3026A is
provided in a space-saving 48-lead MQFP surface mount
plastic package and is specified over the -20
temperature range.
