[原创]ADI AD7606C－18八路18位1 MSPS数据采集系统解决方案

ADI公司的AD7606C-18是八路18位同时取样1 MSPS模拟/数字的数据采集系统(DAC).每一路包括模拟输入箝位保护,可编增益放大器(PGA),低通滤波器(LPF)和18位逐次逼近(SAR)模数转换器(ADC).AD7606C-18还包含灵活的数字滤波器,低漂移2.5V精密基准电压,驱动ADC的基准缓冲器和灵活的并行和串行接口.器件的工作电压为5V,取样吞吐量1 MSPS的输入可为双极单端:±12.5 V, ±10 V, ±6.25 V, ±5 V和±2.5 V;单极单端0 V- 12.5 V, 0 V -10 V和0 V - 5 V以及双极差分±20 V, ±12.5 V, ±10 V和±5 V.器件的SNR为93dB,过取样32时的SNR为102dB,THD为-100dB,FSR最大时的TUE=0.05%.工作温度−40C到 +125C.主要用在动力线监测,保护继电器,多相马达控制,仪器和控制系统,数据采集系统.本文介绍了AD7606C-18主要特性,功能框图,硬件和软件模式连接框图,以及评估板EVAL-AD7606C18FMCZ优势和特点,电路图,材料清单和PCB设计图.

The AD7606C-18 is an 18-bit, simultaneous sampling, analog-to-digital data acquisition system (DAS) with eight channels. Each channel contains analog input clamp protection, a programmable gain amplifier (PGA), a low-pass filter (LPF), and an 18-bit successive approximation register (SAR) analog-to-digital converter (ADC). The AD7606C-18 also contains a flexible digital filter, a low drift, 2.5 V precision reference, a reference buffer to drive the ADC, and flexible parallel and serial interfaces.
