AD10465 Dual Channel, 14-Bit, 65 MSPS A/D Converter With Analog Input Signal Conditioning

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 ADC's. Each AD6644 has a dc-coupled amplifier front end including an AD8037 low distortion, high bandwidth amplifier, providing high input impedance and gain, and driving the AD8138 single to differential amplifier. The AD6644's have on-chip track-and-hold (T/H) circuitry and utilize an innovative multi-pass architecture, to achieve 14-bit, 65 MSPS performance. The AD10465 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 AD10465 operates with ±5.0 V for the analog signal conditioning with a separate +5 V supply for the analog-to-digital conversion and +3.3V 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' MIL-38534 Qualified Manufacturers Line (QML) and components are available up to Class-H (-55°C to +125°C). The AD6644 internal components are manufactured on Analog Devices' high-speed complementary bipolar process (XFCB).
