EUA6211
Advanced Stereo Headphone Amplifier
DESCRIPTION
EUA6211 is a dual audio power amplifier designed for
portable communication device applications such as
mobile phones. EUA6211 operates from a single 2.5V to
5.5V supply, consumes only 3.8mA of supply current,
capable of delivering 30mW of continuous average power
into a 16Ω load from a 3V power supply with a THD+N of
1%.
Base on the power supply delivered to the device, an
internal power management block generates a negative
voltage. Thus, the internal amplifiers provide outputs
referenced to Ground. In this configuration, the two
external heavy coupling capacitors can be removed. It
offers significant space and cost savings compared to a
typical stereo application.
EUA6211 has an internal gain of – 1.5V/V with low 0.03%
THD+N performance. An 80dB at 1kHz power-supply
rejection ratio (PSRR) allows these devices to operate from
noisy digital supplies without an additional linear regulator.
Comprehensive click-and-pop circuitry suppresses audible
clicks and pops on startup and shutdown.
Other features include short-circuit and thermal-overload
protection, and are specified over the extended -40°C to
+85°C temperature range. The device is available in tiny
12- bump WCSP (1.5mm× 2mm) and TDFN-12 packages.
