-The use of just about any generic analog multiplexer integrated circuit is possible with the ADALM1000 to extend the number of voltage input channels. Here are two examples. The first example uses the common CD4052 (or 74HC4052) dual 4:1 analog switch. While the mux can be simply included on your solderless breadboard alongside the rest of the experiment it is often much more convenient to have it on an accessory plug in board as shown. Information and design files for this accessory board can be found in this web page and on GitHub, [[/university/tools/adalm1000/accessory-boards-index#dual_41_analog_input_multiplexer_board| M1k Accessory Board, Dual 4:1 Analog Input Multiplexer]].+The use of just about any generic analog multiplexer integrated circuit is possible with the ADALM1000 to extend the number of voltage input channels.

-Another analog mux board is this one based on the 16:1 CD74HC4067 from [[https://www.sparkfun.com/products/9056|SparkFun Analog/Digital MUX Breakout]]. It does not come with header connectors so they would need to be added. The pins on the connector do not line up with the M1k connectors so male to male jumpers would be needed as shown in the next figure.+Another analog mux board is this one based on the 16:1 CD74HC4067 from [[https://www.sparkfun.com/products/9056|SparkFun Analog/Digital MUX Breakout]]. A similar 8:1 analog multiplexer break-out board using the 74HC4051 circuit is also available from [[https://www.sparkfun.com/products/13906|SparkFun]]. It does not come with header connectors so they would need to be added. The pins on the connector do not line up with the M1k connectors so male to male jumpers would be needed as shown in the next figure.
