AD10265

The AD10265 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 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 highdensity 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-todigital conversion. Each channel is completely independent allowing operation with independent Encode and Analog inputs. 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).
