EVAL-CN0254-SDPZ, Low Cost Isolated Data Acquisition System Evaluation Board based on AD7689, 16-Bit, 250 kSPS, 8-Channel ADC

Beschreibung

• EVAL-CN0254-SDPZ, Isolated data acquisition system Evaluation Board is used the AD7689 16-bit, 8-channel, 250-kSPS PulSAR ADC along with two AD8608 low cost precision quad op amps to provide the entire signal conditioning and digitizing function in the data acquisition system. The only other op amp required is the AD8605 that is used to buffer the reference voltage from the AD7689. The AD8605 and AD8608 are low cost single and quad rail-to-rail input and output CMOS amplifiers. The AD8605 acts as an external reference buffer to provide sufficient driving ability for level shifting. The AD8605 and AD8608 feature very low offset voltage, low input voltage and current noise, and wide signal bandwidth, therefore making them good choices for a wide variety of applications
