HI3026

HI3026 August 1997 8-Bit, 120 MSPS, Flash A/D Converter 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 applications 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 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 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 -20oC to 75oC temperature range.
