TDA8560Q Audio amplifier 2x40W

TDA8560Q general description:Unfortunately, some of the proposed scheme in the network and even a scheme recommended by the developer (Philips), fail to achieve the desired result. As an example of how not to suggest that you include the TDA8560 material published on Online Soldering: Car Amplifier 2x40 Watt (I should note that everything except the input circuits and the number of points on diet, still deserves attention). the initial inclusion of IMS (at power up, the load is connected and there is no input signal) can throw you into a state of perplexity / mild shock (it depends on the degree of hope is for your TDA). Chip is unstable, there are noises when the input signal is amplified last weakly and passed with distortions. IC bypass surgery fixed resistor at the input, the other measures in consultation with the source device does not help. Why and what to do? Really caught Palen chip and will have to buy a new one? Not so fast! The fact that Philips did not include measures t…

5Wx2 10Wx2 25Wx2 40Wx2 Dual BTL class-D power audio amplifier AD199x

GENERAL DESCRIPTION: The AD199x is a two channel Bridge Tied Load (BTL)  switching audio power amplifier with integrated ∑∆ modulator.  The modulator accepts a 1Vrms input signal (maximum power)  and generates a switching waveform to drive speakers directly.  One of the two modulators can control both output stages  providing twice the current for single-channel applications. A digital, microcontroller-compatible interface provides control of reset, mute and PGA gain as well as output signals for thermal and over-current error conditions. The output stage can operate  from supply voltages ranging from 8V to 20V. The analog  modulator and digital logic operate from a 5V supply.

2 × 40 W/2 Ω stereo BTL car radio power amplifier

General description:
The TDA8566 is an integrated class-B output amplifier which is available in several packages. TDA8566TH is contained in a 20-lead small outline plastic package. The TDA8566TH1 is a 24-lead small outline plastic package which is pin compatible with the I2C-bus controlled amplifier TDA1566TH for one board layout. TDA8566Q is a 17-pinDIL-bent-SIL package. The device contains 2 amplifiers in a Bridge-Tied Load (BTL) configuration. The output power is 2 × 25 W in a 4 Ω load or 2 × 40 W in a 2 Ω load. It has a differential input stage and 2 diagnostic outputs. The device is primarily developed for car radio applications.
Features: Differential inputs Very high Common Mode Rejection Ratio (CMRR) High common mode input signal handling Requires very few external components High output power 4 Ω and 2 Ω load driving capability Low offset voltage at output Fixed gain Diagnostic facility (distortion, short-circuit and temperature pre-warning) Good ripple rejection Mode select switch (oper…

2 x 40 W car radio power amplifier

Low dissipation due to switching from Single-Ended (SE) to Bridge-Tied Load (BTL) mode Differential inputs with high Common Mode Rejection Ratio (CMRR) Mute, standby or operating mode selectable by pin Load dump protection circuit Short-circuit safe to ground; to supply voltage and across load Loudspeaker protection circuit Thermal protection at high junction temperature Device switches to single-ended operation at high junction temperature Clip detection at 2.5 % THD Diagnostic signal indicating clipping, short-circuit protection and pre-warning of thermal protection.

The TDA1565TH is a monolithic power amplifier in a 20-lead heatsink small outline plastic package. It contains two identical 40 W amplifiers. Power dissipation is minimized by switching from SE to BTL mode only when a higher output voltage swing is needed. The device is developed primarily for car radio applications.

2x40W Two-Channel Class AB Audio Power Amplifier IC

The STK402-000 series products are audio power amplifier hybrid ICs that consist of optimally-designed discrete component power amplifier circuits that have been miniaturized using SANYO's unique insulated metal substrate technology (IMST). SANYO has adopted a new low thermal resistance substrate in these products to reduce the package size by about 60% as compared to the earlier SANYO STK407-000 series.
