SS8021
Stereo Headphone Power Amplifier
DESCRIPTION
The SS8021 is an output-rail-to-rail stereo audio power
amplifier housed in an 8-pin SOP package capable of
delivering 125mW of continuous power into 16Ω loads
and 75mW into 32 Ω loads with THD <0.1% per
channel.
The gain of the amplifiers can be easily set with two
external resistors - R _{I (input resistor) and RF (feedback}
resistor).
The SS8021 is a dual channel, low voltage, low power,
high performance amplifier. The quiescent current is
typically 3mA at 5V. With excellent AC performance
(small THD), it can be designed into a wide range of
headphone driving applications.
