PRODUCTION DATA
Refer to the PDF data sheet for device specific package drawings
The analog inputs of the ADC3664-SP are intended to be driven differentially. Both AC coupling and DC coupling of the analog inputs is supported. The analog inputs are designed for an input common-mode voltage of 0.95V which must be provided externally on each input pin. Figure 7-2 shows the analog input model of the ADCs. First, 8 switches are closed during acquisition for a period of tACQ. Then, all switches are open for a period of tCONV. Finally, before the next acquisition period, the reset switch is closed for a period of tRST.
