SGM8903 - Capless 3Vrms Line Driver

Description

The SGM8903 is a 3Vrms pop/click-free stereo line driver designed to allow the removal of the output DC-blocking capacitors for reduced component count and cost.

The device is ideal for single supply electronics where size and cost are critical design parameters.

Features

  • Capless Structure Eliminates Pop/Clicks Eliminates Output DC-Blocking Capacitors Provides Flat Frequency Response from DC to 20kHz.
  • Low Noise and THD Typical SNR = 107dB Typical VN = 8μVrms Typical THD+N = 0.001% (f = 1.

SGM8903 Capless 3Vrms Line Driver with Adjustable Gain GENERAL DESCRIPTION The SGM8903 is a 3Vrms pop/click-free stereo line driver designed to allow the removal of the output DC-blocking capacitors for reduced component count and cost. The device is ideal for single supply electronics where size and cost are critical design parameters. The SGM8903 is capable of driving 3Vrms into a 2.5kΩ load with 5V supply voltage. The device has differential inputs and uses external gain setting resistors that supports a gain range of ±1V/V to ±10V/V. The use of external gain resistors also allows the implementation of a 2nd-order low pass filter to compliment DAC's and SOC converters. The SGM8903 has build-in shutdown control for pop/click-free on/off control.
