Analog Devices Inc. ADAS3022 数据采集IC
Analog Devices 与竞争对手的分立器件相比，ADAS3022 数据采集IC只占用1/3的板上空间，有助于工程师简化设计，并缩小高级工业数据采集系统的尺寸。新款16位1MSPS ADI ADAS3022 可用于输电线监控器、过程和电机控制、患者监护，以及其他工业和仪表系统。工作电压范围为 ±10V工业电压。该款数据采集IC集成了 ADI 的 16位 PulSAR® 逐次逼近型 A/D 转换器内核、高阻抗输入缓冲器，以及 7 阶片内可编程增益仪器仪表放大器。ADAS3022 内置1个8通道、低泄漏多路复用器和精密、低漂移4.096V基准电压源。该款ADI IC具有8个数据通道，可提供全16位动态范围，经过优化后，可与工作电压为 ±10V至±640mV的传感器相连接。
The ADI ADAS3022 Data Acquisition IC integrates ADI's 16-bit PulSAR® successive-approximation A/D converter core with high-impedance input buffers and a 7-stage on-chip programmable-gain instrumentation amplifier. ADAS3022 includes an 8-channel, low-leakage multiplexer and precision low-drift 4.096V reference. With eight data channels and delivering full 16-bit dynamic range, this ADI IC is optimized to interface with a wide range of sensors running from ±10V to as low as ±640mV.
