PRODUCT DESCRIPTION
The AD10200 is a full channel ADC solution with on-module
signal conditioning for improved dynamic performance and
fully matched channel-to-channel performance. The module
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).
PRODUCT HIGHLIGHTS
1. Guaranteed sample rate of 105 MSPS.
2. Input signal conditioning with full power bandwidth to
250 MHz.
3. Fully tested/characterized performance at 121 MHz AIN.
4. Optimized for IF sampling.
