NXP Semiconductors TDA8568Q
The TDA8568Q is a integrated class-B output amplifier in a 23-lead Single-In-Line (SIL) plastic power package. It contains four amplifiers in BTL configuration, each with a gain of 40 dB. The output power is 4 × 25 W in a 4 Ω load.FEATURES
● 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 TDA8567Q, except for the gain.
