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.

4. Optimized for IF sampling.
