2.1 Connectors for Analog Inputs

The ADS8354EVM has two 16-bit, simultaneous-sampling ADCs. The ADS8354EVM GUI can either be configured for individual ADC data sampling or simultaneous sampling with both ADCs. The ADS8354EVM is designed to interface to an external, analog source through either subminiature version A (SMA) connectors or 100-mil headers. Jumpers J1, J2, J3, and J4 are the SMA connectors that allow for analog signal source connectivity through coaxial cables. Alternatively, 100-mil jumper cables or mini-grabbers can be used to connect analog sources to pin 1 of connectors JP1, JP2, JP3, and JP4. Table 2-1 lists the analog input connectors for the individual ADCs.

Table 2-1 Analog Input Connector Description
Pin Number Signal Description
J1 and J2 AINM_A, AINP_A Analog inputs provided at the SMA for ADC A
JP2[1] and JP3[1] AINM_A, AINP_A Alternate location to provide the analog inputs for ADC A
J3 and J4 AINM_B, AINP_B Analog inputs provided at the SMA for ADC B
JP1[1] and JP4[1] AINM_B, AINP_B Alternate location to provide the analog inputs for ADC B
