Dual Channel, 12-Bit 105 MSPS IF Sampling
A/D Converter with Analog Input
Signal Conditioning
a
AD10200
FEATURES
Dual, 105 MSPS Minimum Sample Rate
Channel-Channel Isolation, >80 dB
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
AC-Coupled Signal Conditioning Included
Gain Flatness up to Nyquist: < 0.2 dB
Input VSWR 1.1:1 to Nyquist
80 dB Spurious-Free Dynamic Range
Two’s Complement Output Format
3.3 V or 5 V CMOS-Compatible Output Levels
0.850 W per Channel
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).
