Features and Overview

  • High impedance input
  • Input signals may be rail-to-rail
  • Can be used with RefMux to multiplex input signals to switch capacitor block
  • Programmable control of input source

The AMUX8 User Module provides an eight-input-analog-signal-multiplexer to a Continuous Time (CT) block, controlled by an API. One of four input signals may be selected to the input of the amplifier in the CT block. These input signals are connected to fixed ports, depending on which column the user module is placed. The module is also used in conjunction with a RefMux to route the multiplexed signals to the analog column bus.

The AMUX8 User Module is used when the application needs to dynamically select from two or more ports during operation.
