GENERAL DESCRIPTIONThe AD9054A 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 AD9054A
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 AD9054A’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 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.
AD9054A–SPECIFICATIONS
ELECTRICAL CHARACTERISTICS(VDD = 5 V, external reference, fS = max unless otherwise noted.)
AD9054ANOTESGain error and gain temperature coefficient are based on the ADC only (with a fixed 2.5 V external reference).3 dB bandwidth with full-power input signal.tV and tPD are measured from the threshold crossing of the ENCODE input to valid TTL levels of the digital outputs. The output ac load during test is 5 pF (Refer to
equivalent circuits Figures 5 and 6).IIH and IIL are valid for differential input voltages of less than 1.5 V. At higher differential voltages, the input current will increase to a maximum of 1.5 mA.Power dissipation is measured under the following conditions: analog input is –1 dBFS at 19.7 MHz.Typical thermal impedance for the ST-44 (LQFP) 44-lead package (in still air): θJC = 20°C/W, θCA = 35°C/W, θJA = 55°C/W.A change in input offset voltage with respect to a change in VDD.SNR/harmonics based on an analog input voltage of –1.0 dBFS referenced to a 1.024 V full-scale input range.

CAUTIONESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the AD9054A features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
