High Performance, Bipolar-Input, Ultra-Low Noise HiFi Audio Headset Driver
GENERAL DESCRIPTION

The dual SGM8261-5 is a bipolar-input, low noise headset driver optimized for high voltage systems. The device operates from 3.6V to 36V single supply or from ±1.8V to ±18V dual power supplies, while consuming 4.1mA quiescent current per amplifier.

The SGM8261-5 has impressive dynamic characteristics with various loads. The rail-to-rail output swing with a 2kΩ load is within 150mV of the rails. This results in large headroom and wide dynamic range. The SGM8261-5 is unity-gain stable and offers a ±110mA high output current. It features 1.6nV/√Hz ultra-low noise at 1kHz with 0.00002% distortion.

The SGM8261-5 is available in Green MSOP-10 and TDFN-3×3-10L packages. It operates over an ambient temperature range of -40 to +85.
