The application requirements are provided in Table 8-1. Since the supported signal bandwidth is as low as DC, an amplifier is used to DC couple the signal to the input of the ADC. Additionally, the ADC VCM output provides the amplifier common-mode as shown in Figure 8-1.
When designing the amplifier or filter driving circuit, the ADC input full-scale voltage needs to be taken into consideration. For example, the ADC3664-SP input full-scale is 3.2VPP. Texas Instruments (TI) offers a variety of amplifiers to be used in space applications such as LMH5485-SP and THS4511-SP. For best DC accuracy an external reference can be used.
