Texas Instruments ADS8588H/ADS8598H同步采样ADC
Texas Instruments ADS8588H/ADS8598H同步采样ADC是基于逐次逼近 (SAR) 模数转换器 (ADC) 的集成数据采集 (DAQ) 系统。ADS8588H/ADS8598H可对所有输入通道同时采样，从而实现每通道500kSPS的最大吞吐量。该器件的每个通道都有一个完整的模拟前端，其中包含输入阻抗高达1MΩ的可编程增益放大器 (PGA)、低通滤波器、输入钳位以及ADC输入驱动器。此外，该器件还设有缓冲器，可通过低漂移、精密基准电压来驱动ADC。凭借支持串行、并行和并行字节通信的灵活数字接口，该ADC适用于各种主机控制器。ADS85xH采用单一5V电源，并且可配置为接受±10V或±5V真正双极输入。高阻抗特性允许直连传感器和变压器，因此无需使用外部驱动器电路。ADS8588H/ADS8598H能够实现高性能、高精度以及零延迟转换，因此可满足大量工业自动化和控制应用的严格设计要求。
Additionally, the device has a buffer to drive the ADC through a low-drift, precision reference. The ADC can be used with various host controllers using a flexible digital interface supporting serial, parallel, and parallel byte communication. Using a single 5V supply, the ADS8588H/ADS8598H can be configured to accept ±10V or ±5V true bipolar inputs.
The need for external driver circuits is eliminated through the high impedance allowing direct connection with sensors and transformers. The ADS8588H/ADS8598H meets the strict design requirements for many industrial automation and control applications through high performance, accuracy, and zero-latency conversions.
