IS31AP4912 - STEREO HEADPHONE DRIVER

General Description

The IS31AP4912 is stereo headphone drivers designed to allow the removal of the output DC-blocking capacitors for reduced component count and cost.

The IS31AP4912 is ideal for small portable electronics where size and cost are critical design parameters.

Key Features

  • No output DC-blocking capacitors Supply voltage from 2.7V ~ 5.5V Low output noise (7µV) High SNR (103dB) -95dB PSRR Thermal protect circuit Integrated click-and-pop suppression circuitry UTQFN-12 (2mm × 2mm) package.
