AD10465: 双通道、14位、65 MSPS ADC，内置模拟输入信号调理电路
AD10465是一款内置信号调理电路模块的全通道ADC解决方案，提供改进的动态性能和完全匹配的通道间性能。该模块包括两个宽动态范围AD6644 ADC，各AD6644均有一个采用低失真、高带宽放大器AD8037的直流耦合放大器前端，可提供高输入阻抗和增益，并驱动单端转差分放大器AD8138。AD6644具有片内采样保持(T/H)电路，并采用创新的多通架构，可实现14位、65 MSPS性能。AD10465利用创新的高密度电路设计和激光调整的薄膜电阻网络实现出色的匹配和性能，同时保持极佳的隔离特性，并大幅缩小电路板面积。AD10465的模拟信号调理部分采用±5.0 V电源供电，模数转换部分则采用单独的+5.0 V电源供电，输出级采用+3.3V数字电源供电。每个通道均完全独立，可以在独立的编码和模拟输入下工作。AD10465还允许用户选择模拟输入信号范围，从而最大程度地减少额外的外部信号调理，同时仍然保持通用性。AD10465采用68引脚陶瓷鸥翼式封装，尺寸兼容先期产品AD10242（12位、40 MSPS）和AD10265（12位、65 MSPS）。它采用ADI公司的MIL-38534认证制造线(QML)制造，提供最高达H级的工作温度范围（-55°C至+125°C）。AD6644内部元件采用ADI公司的高速互补双极性工艺(XFCB)制造。
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).
