EUA6210
Headphone Amplifier
Output Capacitor-less 67mW Stereo
DESCRIPTION
The EUA6210 is an audio power amplifier primarily
designed for headphone applications in portable device
applications. It is capable of delivering 67mW of
continuous average power per channel into a 16Ω load
with less than 1% distortion (THD+N) from a 3.3V power
supply.
The EUA6210 utilizes a new circuit topology that
eliminates output coupling capacitors and half-supply
bypass capacitors. It is ideally suited for low-power
portable applications where minimal space and power
consumption are primary requirements.
The EUA6210 is also unity-gain stable and can be
configured by external gain-setting resistors. Other features
include click/pop suppression, low-power shutdown mode
and thermal shutdown protection.
