AD10465

NOTES
1 Absolute maximum ratings are limiting values applied individually, and beyond which the serviceability of the circuit may be impaired. Functional operability is not necessarily implied. Exposure to absolute maximum rating conditions for an extended period of time may affect device reliability.
2 Typical thermal impedance for "ES" package: _JC = 2.2°C/W; _JA = 24.3°C/W.

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).
