TDA1519 power amplifier circuit, TDA1519CL is a 2x11w audio power amplifier chip, single power supply, fewer components and simple circuit. BTL power can reach 22w.
The TDA1519C is a class-B dual output amplifier integrated into a 9-lead plastic single in-line power package or a 20-lead heatsink small outline package. In the TDA1519CTH (SOT418-3) version, the heatsink is placed on top of the package, enabling the mounting of an external heatsink. The TDA1519CTD (SOT397-1) has the heatsink facing the PCB, allowing for it to be soldered onto the copper area of the PCB.

Features TDA1519 power amplifier circuit TDA1519CL
- Requires very few external components for Bridge-Tied Load (BTL) operation
- Stereo or BTL application
- High output power
- Low offset voltage at output (important for BTL applications)
- Fixed gain
- Good ripple rejection
- Mute/standby switch
- Load dump protection
- AC and DC short-circuit safe to ground and VP
- Thermally protected
- Reverse polarity safe
- Capability to handle high energy on outputs (V P = 0 V)
- No switch-on/switch-off plops
- Protected against electrostatic discharge
- Low thermal resistance
- Identical inputs (inverting and non-inverting)
- Pin compatible with TDA1519B (TDA1519C and TDA1519CSP).
In this circuit use TDA1519C SIL9P plastic single in-line power package; 9 leads
The TDA1519C is equipped with two identical amplifiers, each with a fixed gain of 40 dB and differential input stages. One notable feature of this device is the mute/standby switch, offering the following capabilities:
- Low standby current (<100 µA)
- Low mute/standby switching current (allows for low-cost supply switch)
- Mute condition.
