DIO2162中文资料2-Vrms Audio Driver with Programmable-Fixed Gain数据手册DIOO规格书

描述 Description

The DIO2162 is a single-ended, 2Vrms stereo audio driver, reducing component count, board space and cost. It is ideal for single-supply electronics where size and cost are critical design parameters.
The DIO2162 can generate 5.6Vpp output voltage within 3.3V supply, and driving 2Vrms into a 600? Load. The device has fixed-gain single-ended inputs with a gain-select pin. Using a single resistor on this pin, the designer can choose from 13 internal programmable gain settings to match the audio driver with the codec output level. It also reduces the component count and board space.
Audio outputs have 5kV HBM ESD protection, enabling a simple ESD protection circuit. The DIO2162 has built-in active mute control with more than 80dB attenuation for pop-free mute on/off control.
