AD13465中文资料Dual Channel, 14-Bit, 65MSPS A/D Converter with Analog Input Signal Conditioning数据手册ADI规格书

描述 Description

The AD13465 is a complete dual channel signal processing solution including on-board amplifiers, references, ADCs, and output termination components to provide optimized system performance. The AD13465 has on-chip track-and-hold circuitry and utilizes an innovative multipass architecture to achieve 14-bit, 65 MSPS performance. The AD13465 uses state-of-the-art, high density circuit design and laser-trimmed thin-film resistor networks to achieve exceptional channel matching and impedance control, and provide for significant board area savings.

Multiple options are provided for driving the analog input, including single-ended, differential, and optional series filtering. The AD13465 also offers the user a choice of analog input signal ranges to further minimize additional external signal conditioning, while remaining general-purpose. The AD13465 operates with ±5.0 V for the analog signal conditioning, 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, while maintaining minimal crosstalk and interference.

The AD13465 is packaged in a 68-lead ceramic gull wing package. Manufacturing is done on Analog Devices’ MIL-38534 Qualified Manufacturers Line (QML) and components are available up to Class-H (–40°C to +85°C). The components are manufactured using Analog Devices’ high speed complementary bipolar process (XFCB).
