The module includes two wide dynamic range AD6644 ADCs. Each AD6644 has a dc- coupled 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 ampli- fier. 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 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 condi- tioning 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 fur- ther 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). Manufac- turing 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 comple- mentary 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. 5. Footprint compatible family; 68-lead LCC. |
