Description

The HI3086 is a 6-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 200MHz, this HI3086 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 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 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 to 75 temperature range.
