Showing posts with the label TDA8571J

4 × 40 W BTL quad car radio power amplifier

Requires very few external components High output power Low output offset voltage Fixed gain Diagnostic facility (distortion, short-circuit and temperature pre-warning) Good ripple rejection Mode select switch (operating, mute and standby) Load dump protection Short-circuit safe to ground and to VP and across the load Low power dissipation in any short-circuit condition Thermally protected Reverse polarity safe Electrostatic discharge protection No switch-on/switch-off plop Flexible leads Low thermal resistance Pin compatible with the TDA8568Q, except for the gain.
The TDA8571J is a integrated class-B output amplifier contained in a 23-lead Single-In-Line (SIL) plastic power package. It contains four amplifiers in a BTL configuration, each with a gain of 34 dB. The output power is 4 × 40 W (EIAJ) into a 4 Ω load.
Primarily developed for car radio applications
