AD10465

The AD10465 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 AD6644 ADCs. Each AD6644 has a dccoupled amplifier front end including an AD8037 low distortion,high bandwidth amplifier, providing a high input impedance and gain, and driving the AD8138 single-to-differential amplifier.

The AD6644s have on-chip track-and-hold circuitry and utilize an innovative multipass architecture to achieve 14-bit,65 MSPS performance. The AD10465 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 AD10465 operates with ±5.0 V for the analog signal conditioning with a separate 5.0 V supply for the analog-to-digital conversion and 3.3 V digital supply for the output stage. Each channel is completely independent, allowing operation with independent encode and analog inputs. The AD10465 also offers the user a choice of analog input signal ranges to further minimize additional external signal conditioning, while still remaining general-purpose.

The AD10465 is packaged in a 68-lead Ceramic Gull Wing package, footprint-compatible with the earlier generation AD10242 (12-bit, 40 MSPS) and AD10265 (12-bit, 65 MSPS). Manufacturing is done on Analog Devices, Inc. Mil-38534 Qualified Manufacturers Line (QML) and components are available up to Class-H (40°C to +85°C). The AD6644 internal components are manufactured on Analog Devices, Inc. high-speed complementary bipolar process (XFCB).
