Features and Overview

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

The AMux4 User Module provides a four input analog signal multiplexer to a Continuous Time (CT) block that can be controlled programmatically by way of 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 this user module is placed. This module can also be used in conjunction with a RefMux to route the multiplexed signals to the analog column bus.
