Descriptions
The DIO2112H is an integrated solution for
Set-top box and high definition player, and
designed to optimize the audio driver circuit
performance while reducing the BOM cost by
eliminating the peripheral discrete components
for noise reduction. DIO2112H features a 2Vrms
stereo audio driver that designed to allow for the
removal of output AC-coupling capacitors.
Featuring differential input mode, gain range of
±1 V/V to ±10 V/V can be achieved via external
gain resistor setting. The DIO2112H is able to
offer 2Vrms output with 10kΩ load and 3.3V
supply.
Meanwhile, the DIO2112H offers built-in
shut-down control circuitry for optimal pop-free
performance. Under the under-voltage condition,
DIO2112H is able to detect it and mutes the
output.
