The AD9054A’s encode input interfaces directly to TTL, CMOS The AD9054A is an 8-bit monolithic analog-to-digital converter or positive-ECL logic and will operate with single-ended or optimized for high speed, low power, small size and ease of use. differential inputs. The user may select dual-channel or single- With a 200 MSPS encode rate capability and full-power analog channel digital outputs. The dual (demultiplexed) mode inter- bandwidth of 350 MHz, the component is ideal for applications leaves ADC data through two 8-bit channels at one-half the requiring the highest possible dynamic performance. clock rate. Operation in demultiplexed mode reduces the speed To minimize system cost and power dissipation, the AD9054A and cost of external digital interfaces while allowing the ADC to includes an internal 2.5 V reference and track-and-hold circuit. be clocked to the full 200 MSPS conversion rate. In the single- The user provides only a 5 V power supply and an encode clock. channel (nondemultiplexed) mode, all data is piped at the full No external reference or driver components are required for clock rate to the Channel A outputs. many applications. Fabricated with an advanced BiCMOS process, the AD9054A is provided in a space-saving 44-lead LQFP surface mount plastic package (ST-44) and specified over the full industrial (–40°C to +85°C) temperature range.
