Input Connections

3.1 Input Connections
Analog input is via a screw terminal – J2. The input can be single ended or
differential.
Bias current and voltage for an external microphone is provided via a screw
terminal – J3.
3.2 Output Connections
The output from the AIC111 is from an H-bridge driver. These output topologies
generally require a filter to recover the analog output signal. The output signal
is available at J4.
The prototype area on the EVM can be used to build a simple filter, or
alternatively, it is possible to build a small conditioning board which fits on top
of the prototype area. Check with the factory for availability of filter boards.
Convenient points for picking-up the H-bridge ground are located around the
prototype area and are indicated on the silkscreen by circles around the plated
through holes.
