  • Page 6: Functional Description

    FUNCTIONAL DESCRIPTION A data flow block diagram of the * is presented in Figure 1-1. The IP-48ADM16 has 6 fault-protected CMOS analog multiplexers. Each multiplexer has 8 inputs and one common output. These outputs are acquired by differential multiplexers. The differential inputs can then be configured for single-ended, differential, or calibration modes.

    More information is available at www.analogdevices.com. 2.2.1 Acquisition Mode Setting up the IP-48ADM16 for acquisition is done in several steps: 1) select the Scan clock source: • Internal with the internal timer (the divisor needs to be programmed as well.
  • Page 10: Continuous Mode

    Setting the DATARAM pointer with a desired address lower than the End address or a number of scan lower than the total scan and enabling an interrupt, the host can “throttle” the read of A/D data.
