DIO2128

3-Vrms Audio Driver with Adjustable Gain

Description

The DIO2128 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. DIO2128 features a 3Vrms stereo audio driver that designed to allow for the removal of output AC-coupling capacitors.

Featuring differential input mode, gain range of ±1V/V to ±10V/V can be achieved via external gain resistor setting. The DIO2128 is able to offer 3Vrms output at 600Ω load with 5V supply.

Meanwhile, the DIO2128 offers built-in shut-down control circuitry for optimal pop-free performance. Under under-voltage condition, DIO2128 is able to detect it and mutes the output.
