TDA7560 Audio Amplifier 4x50W

TDA7560 general description:

TDA7560 is a 4 x 45W QUAD BRIDGE car audio amplifier plus HSD. The TDA7560’s inputs are ground-compatible and can stand very high input signals (± 8Vpk) without any performances degradation. If the standard value for the input capacitors (0.1mF) is adopted, the low frequency cut-off will amount to 16 Hz. The TDA7560 is a breakthrough BCD (Bipolar / CMOS / DMOS) technology class AB Audio Power Amplifierin Flexiwatt 25 package designed for high power car radio. The fully complementary P-Channel/N-Channel output structure allows a rail to rail output voltage swing which, combined with high output current and minimised saturation losses sets new power references in the car-radio field, with unparalleled distortion performances.

TDA7560 features:

• 4 x 50W/4W MAX.
• 4 x 45W/4W EIAJ
• 4 x 30W/4W @ 14.4V, 1KHz, 10%

4 x 45W Audio Power Amplifier

General description:

The TDA8595 is a complementary quad Bridge Tied Load (BTL) audio power amplifier made in BCDMOS technology. It contains four independent amplifiers in BTL configuration. Through the I2C-bus, diagnosis of temperature warning and clipping level is fully programmable and the information available via two diagnostic pins is selectable. The status of each amplifier (output offset, load or no load, short-circuit or speaker incorrectly connected) can be read separately.

Features and benefits:

• Operates in legacy mode (non I2C-bus) and I2C-bus mode (3.3 V and 5 V compliant)
• Three hardware-programmable I2C-bus addresses
• Drive 4  or 2  loads
• Speaker fault detection
• Independent short-circuit protection per channel
• Loss of ground and open VP safe (with 150 m series impedance and a supply  decoupling capacitor of 2200 F maximum)
• All outputs short-circuit proof to ground, supply voltage and across the load
• All pins short-circuit proof to ground
• Temperature-controlled gain reduction to prevent audio holes at high junction temperatures
• Low battery voltage detection
• Offset detection
• This part has been qualified in accordance with AEC-Q100

4x45W Stereo Power Amplifier Circuit Diagram TDA8596

General description:

The TDA8596 is a quad Bridge Tied Load (BTL) audio power amplifier with symmetrical inputs, made in BCDMOS technology. It contains four independent amplifier channels in BTL configuration with complementary (PMOST/NMOST) output stages. Temperature warning and output signal clipping diagnosis is possible via the I2C-bus and via the diagnostic pins (DIAG and STB pin). The temperature pre-warning level and clip detection levels can be programmed via the I2C-bus. The status of each amplifier channel (i.e. output offset, load connected or not, short circuit condition at the output pins) can be read out separately.

Features

• Operates in legacy mode (non I2C-bus) and I2C-bus mode (3.3 V and 5 V compliant)
• Three hardware-programmable I2C-bus addresses
• Drives 4 Ω or 2 Ω loads
• Balanced/symmetrical inputs
• Speaker fault detection
• Programmable gain (26 dB and 16 dB) also available in legacy mode
• Independent short circuit protection per channel
• Loss of ground and loss of VP safe (with 300 mΩ series impedance and a maximum supply decoupling capacitor of 2200 µF)
• All outputs are short-circuit proof to ground, supply voltage and across the load
• All pins are short circuit proof to ground
• Temperature-controlled gain reduction to prevent audio holes at high junction temperatures
• Low battery voltage detection
• Qualified in accordance with AEC-Q100
