The module includes two wide dynamic range AD6640 ADCs. Each AD6640 has an AD9631/AD9632 ac-coupled amplifier front end. The AD6640s have on-chip track-and-hold circuitry, and utilize an innovative multipass architecture, to achieve 12-bit, 65 MSPS performance. The AD10265 uses innovative high- density circuit design and laser-trimmed thin-film resistor networks to achieve exceptional matching and performance while still maintaining excellent isolation, and providing for significant board area savings. The AD10265 operates with ± 5.0 V for the analog signal conditioning with a separate +3.3 V supply for the analog-to- digital conversion. Each channel is completely independent allowing operation with independent Encode and Analog in- puts. The AD10265 also offers the user a choice of Analog Input Signal ranges to further minimize additional external signal conditioning, while still remaining general-purpose. The AD10265 is packaged in a 68-lead Ceramic Gull Wing Package, footprint compatible with the earlier generation AD10242 (12-bit, 40 MSPS). Manufacturing is done on Analog Devices’ MIL-38534 Qualified Manufacturers Line (QML) and components are available up to Class-H (–55 °C to +125 °C). The AD6640 internal components are manufactured on Analog Devices’ high speed complementary bipolar process (XFCB). PRODUCT HIGHLIGHTS 1. Guaranteed sample rate of 65 MSPS. 2. Input amplitude options, user configurable. 3. Input signal conditioning included; both channels matched for gain. 4. Fully tested/characterized performance for full channel. 5. Footprint compatible family; 68-lead LCCC. One Technology Way, P.O. Box 9106, Norwood, MA 02062-9106, U.S.A.
