LINEAR INTEGRATED CIRCUIT
1W BTL AUDIO AMPLIFIER
DESCRIPTION
The UTC TDA8541(T) is a 1W BTL audio amplifier ,which has
a complementary PNP-NPN output stage and standby/mute logic,
it uses UTC’s advanced technology to provide customers with low
saturation voltage of output stage, low standby current and high
SVRR, etc.
SOP-8
FEATURES
* Low saturation voltage of output stage
* External resistors could fix Gain
* Low standby current
* No switch-on/switch-off plops
* High SVRR
* Protected against outputs short-circuit to ground, VCC and
across the load
* Thermal shut-down protection

Notes: 1. With a load connected at the outputs the quiescent current will increase, the maximum of this increase
being equal to the DC output offset voltage divided by RL.
2. The DC output voltage with respect to ground is approximately 0.5×VCC

Notes: 1. Gain of the amplifier is 2×R2/R1 in test circuit of Figure 1.
2. The noise output voltage is measured at the output in a frequency range from 20Hz to 20kHz (unweighted),
with a source impedance of RS=0ꢀ at the input.
3. Supply voltage ripple rejection is measured at the output, with a source impedance of RS=0ꢀ at the input.
The ripple voltage is a sine wave with a frequency of 1kHz and an amplitude of 100mV (RMS), which is
applied to the positive supply rail.
4. Supply voltage ripple rejection is measured at the output, with a source impedance of RS=0ꢀ at the input.

The ripple voltage is a sine wave with a frequency between 100Hz and 20kHz and an amplitude of 100mV
(RMS), which is applied to the positive supply rail.
5. Output voltage in mute position is measured with an input voltage of 1V (RMS) in a bandwidth of 20kHz, so
including noise.
