The IP-48AD-16 module contains 48 simultaneous channels of A/D conversion using a 16-bit, fast, successive approximation A/D’s. The module can accept bipolar input signals at rates up to 250ksps, and the analog input signals are buffered with a fast buffer amplifier. The A/D contains low noise, wide bandwidth track-and-hold amplifiers that can handle input frequencies up to 8MHz.
The acquisition can be started by the host, a write to the IP register, activation of the IPSTROBE signal, or an external trigger. A state machine will read the data of each individually selected A/D channel into the FIFO.
FIFO pointers are used to monitor, stop or “throttle” the acquisition and inform the user by means of status or interrupt the progress of the acquired data.
The A/D converter data can be read directly by the host if desired bypassing the FIFO. The sampling clock is available from an internal divider and the TCLK0 input, IPSTROBE signal, an external clock, or the host. Sampling occurs with A/D pairs.
The board ID can be read from the on-board EEPROM.
