ADAQ7980BCCZ描述

ADAQ7980/ADAQ7988均为16位模数转换器(ADC)子系统，系统中集成四个常见信号处理和调理模块，采用支持各种应用的封装(SiP)设计。这些器件集成最关键的无源元件，从而消除与使用逐次逼近寄存器(SAR) ADC的传统信号链相关的许多设计挑战。这些无源元件对于实现指定的器件性能至关重要。

ADAQ7980/ADAQ7988内置一个高精度、低功耗、16位SAR ADC，一个低功耗、高带宽、高输入阻抗ADC驱动器，一个稳定的低功耗基准电压缓冲器和一个高效的电源管理模块。这些系统采用5 mm × 4 mm小型LGA封装，可简化数据采集系统的设计过程。ADAQ7980/ADAQ7988的系统集成度解决了许多设计挑战难题，同时提供灵活的可配置ADC驱动器反馈环路，以便调整增益和/或共模。一组四个器件电源提供出色的系统性能；但是，可实现单电源工作且对器件工作规格的影响很小。

SPI兼容串行接口能够利用SDI输入将多个器件以菊花链形式连结到单三线式总线上，并提供一个可选的繁忙指示。用户接口与1.8 V、2.5 V、3 V或5 V逻辑兼容。这些器件的额定工作温度范围为−55°C至+125°C。

EVAL-ADAQ7980SDZ产品详情

The EVAL-ADAQ7980SDZ is an evaluation board designed to demonstrate the low power ADAQ7980 performance and provide an easy to understand interface for a variety of system applications. The ADAQ7980 is a 16-bit analog-to-digital converter (ADC) subsystem that integrates four common signal processing and conditioning blocks into a system in package (SiP) design that supports a variety of applications.

The EVAL-ADAQ7980SDZ can also evaluate the ADAQ7988, despite being populated with the ADAQ7980. To mimic the evaluation of the ADAQ7988 performance, limit the maximum sample rate of the ADAQ7980 to 500 kSPS in the ADAQ798x Evaluation Software.

The evaluation board is ideal for use with the Analog Devices, Inc., system demonstration platform (SDP) board, EVAL-SDP-CB1Z. The EVAL-ADAQ7980SDZ interfaces to the SDP board via a 120-pin connector. SMA Connectors P1, P2, P3, and P4 are provided to connect a low noise analog signal source.

The ADAQ798x Evaluation Software executable controls the evaluation board over the USB through the EVAL-SDP-CB1Z.

A full description and complete specifications for the ADAQ7980 are provided in the ADAQ7980/ADAQ7988 data sheet and should be consulted in conjunction with this user guide when using the evaluation board. Full details on the EVAL-SDP-CB1Z are available on the SDP-B product page.
