The HI3286 is an 8-bit, high-speed, flash analog-to-digital converter optimized for high speed, low power, and ease of use. With a 160MSPS encode rate capability and full-power analog bandwidth of 250MHz, 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 HI3286 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 160MSPS conversion rate. Fabricated with an advanced Bipolar process, the HI3286 is provided in a space-saving 48 lead LQFP surface mount plastic package and is specified over the -20^oC to 75^oC temperature range.
