GENERAL DESCRIPTION
The AD9054 is an 8-bit monolithic analog-to-digital converter
optimized for high speed, low power, small size and ease of use.
With a 200 MSPS encode rate capability and full-power analog
bandwidth of 350 MHz, the component is ideal for applications
requiring the highest possible dynamic performance.
To minimize system cost and power dissipation, the AD9054
includes an internal +2.5 V reference and track-and-hold circuit.
The user provides only a +5 V power supply and an encode
clock. No external reference or driver components are required
for many applications.

The AD9054’s encode input interfaces directly to TTL, CMOS
or positive-ECL logic and will operate with single-ended or
differential inputs. The user may select dual-channel or single-
channel digital outputs. The dual (demultiplexed) mode inter-
leaves ADC data through two 8-bit channels at one-half the
clock rate. Operation in demultiplexed mode reduces the speed
and cost of external digital interfaces while allowing the ADC to
be clocked to the full 200 MSPS conversion rate. In the single-
channel (nondemultiplexed) mode, all data is piped at the full
clock rate to the Channel A outputs.
Fabricated with an advanced BiCMOS process, the AD9054 is
provided in a space-saving 44-lead TQFP surface mount plastic
package (ST-44) and specified over the full industrial (–40°C to
+85°C) temperature range.
