22 W bridge/stereo audio amplifier with clipping detector

Leave a Comment
Features:
  • Very few external components
  • No Boucherot cells
  • No bootstrap capacitors
  • High output power
  • No switch on/off noise
  • Very low standby current
  • Fixed gain (20 dB stereo)
  • Programmable turn-on delay
  • Clipping detector
  • Protections:
  • Output AC-DC short circuit to ground and to supply voltage
  • Very inductive loads
  • Loudspeaker protection
  • Overrating chip temperature
  • Load dump voltage
  • Fortuitous open ground
  • ESD

Description:

The TDA7360 is a new technology class AB Audio Power Amplifier in the Multiwatt® package designed for car radio applications. Thanks to the fully complementary PNP/NPN  output configuration the high power performance  of the TDA7360 is obtained without bootstrap  capacitors.
A delayed turn-on mute circuit eliminates audible  on/off noise, and a novel short circuit protection system prevents spurious intervention with highly  inductive loads. The device provides a circuit for the detection of  clipping in the output stages. The output, an open  collector, is able to drive systems with automatic  volume control.

4x45W Stereo Power Amplifier Circuit Diagram TDA8596

Leave a Comment
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

2 x 40 W car radio power amplifier

Leave a Comment
FEATURES

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.


GENERAL DESCRIPTION

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.
