Rev 1.2 DIO2128 3-Vrms Audio Driver with Adjustable Gain Features Descriptions Voltage Output at 600 Load The DIO2128 is an integrated solution for Set-top box and high definition player, and designed to 2Vrms with 3.3V supply voltage optimize the audio driver circuit performance 3Vrms with 5.0V supply voltage while reducing the BOM cost by eliminating the Ultra Low noise and THD peripheral discrete components for noise SNR>112dB reduction. DIO2128 features a 3Vrms stereo Typical Vn<5.1Vrms audio driver that designed to allow for the THD+N>100dB removal of output AC-coupling capacitors. No Pop/Clicks Noise when Power ON/OFF Featuring differential input mode, gain range of No Need for Output DC-Blocking Capacitors 1V/V to 10V/V can be achieved via external Optimized Frequency Response between gain resistor setting. The DIO2128 is able to offer 20Hz20kHz 3Vrms output at 600 load with 5V supply. Accepting Differential Input Meanwhile, the DIO2128 offers built-in shut-down Featuring external under voltage mute control circuitry for optimal pop-free HBM ESD protection: Output pin 8kV performance. Under under-voltage condition, Available in EP-MSOP-10 package DIO2128 is able to detect it and mutes the output.
