DESCRIPTION
Channel 1 Input
Channel 2 Input
Channel 3 Input
Channel 4 Input
Internal reference bypass capacitor connection
Logic input, ACTIVE LOW. Setting SLEEP to low puts the
TAA4100A in sleep mode. This pin must be driven high via an
external power supply or microcontroller for the TAA4100A to
begin operation. Input range is 0 to 5V with 3.3V compliant
inputs.
Logic input, ACTIVE HIGH. Enables Analog Mode operation.
Typically driven by an external power supply of microcontroller.
Input range is 0 to 5V with 3.3V compliant inputs.
Logic output, ACTIVE LOW. OVRLDB low indicates the input
has overloaded the amplifier
Logic Input, ACTIVE LOW. Setting MUTE to low puts the device
in mute mode. Typically driven by external power supply or
microcontroller. Input range is 0 to 5V with 3.3V compliant
inputs.
Analog ground
On chip 5V regulator bypass capacitor connection
Logic output, ACTIVE LOW. HMUTEB low indicates TAA4100A
is in mute mode
