a
Dual Channel, 12-Bit 105 MSPS IF Sampling
A/D Converter with Analog Input
Signal Conditioning
AD10200
includes two wide-dynamic range ADCs. Each ADC has a
transformer coupled front-end optimized for Direct-IF sampling.
The AD10200 has on-chip track-and-hold circuitry, and utilizes
an innovative architecture to achieve 12-bit, 105 MSPS perfor-
mance. The AD10200 uses innovative high-density circuit
design to achieve exceptional matching and performance while
still maintaining excellent isolation, and providing for significant
board area savings.
The AD10200 operates with 5.0 V supply for the analog-to-
digital conversion. Each channel is completely independent
allowing operation with independent encode and analog inputs.
The AD10200 is packaged in a 68-lead ceramic chip carrier
package. Manufacturing is done on Analog Devices, Inc. MIL-
38534 Qualified Manufacturers Line (QML) and components
are available up to Class-H (–55°C to +125°C).

NOTES

Gain Error measured at 2.5 MHz.

Input VSWR guaranteed 10 MHz to 200 MHz.
4
t
V
and t
PD
are measured from the transition points of the ENCODE input to the 50%/50% levels of the digital outputs swing. The digital output load during test is
not to exceed an ac load of 10 pF or a dc current of
±
40 mA.
5
Supply voltages should remain stable within
±
5% for normal operation.
6
Power dissipation measured with encode at rated speed and 0 dBm analog input.
7
Analog Input signal power at –1 dBFS; signal-to-noise ratio (SNR) is the ratio of signal level to total noise (first 5 harmonic removed). Encode = 105 MSPS. SNR
is reported in dBFS, related back to converter full scale.
8
Analog Input signal power at –1 dBFS; signal-to-noise and distortion (SINAD) is the ratio of signal level to total noise + harmonics. Encode = 105 MSPS. SINAD
is reported in dBFS, related back to converter full scale.
9
Analog Input signal equal –1 dBFS; SFDR is ratio of converter full scale to worst spur.
10
Both input tones at –7 dBFS; two tone intermodulation distortion (IMD) rejection is the ratio of either tone to the worst third order intermod product. f1 = x MHz
±
100 kHz, f2 = x MHz

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the AD10200 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.
