STEREO CAR RADIO
POWER AMPLIFIER
DESCRIPTION
The UTC TDA1519B is an integrated class - B dual
output amplifier. It contains two identical amplifiers with
differential input stages. The gain of each amplifier is fixed
at 40dB. The device is primarily developed for car radio
application.

Notes: 1. Output power is measured directly at the output pins of the device.
2. Frequency response externally fixed.
3. Ripple rejection measured at he output with a source impedance of 0Ω(maximum ripple amplitude of 2V).
4. Frequency f =100Hz
5. Frequency between 1kHz and 10kHz
6. Noise output voltage independent of Rs (VI=0V)
