A power-amp designed for use in low voltage battery operated equipment where a high output power is still required. By using the Bridge Tied Load principle in the amp an output power of 1.2W into 8 Omega is achieved from a 6V supply. The gain of the amplifier is fixed internally at 40d B & almost no external components are required. The amp is short-circuit proof requires no external heatsink & there are no switch-on or switch-off clicks. ...

Product Description


- Provides a high output current capability of up to 3.5A & very low harmonic & crossover distortion
- Designed for single-ended supply operation in the range 8 to 18V & applications including in-car stereos & radios The device can output 6W into a 4 Omega load from a 14.4V supply & up to 12W into loads down to 1.6 Omega. Two can be used to form a bridge delivering 18W into 4 Omega from a 14.4V supply. Completely safe operation is guaranteed due to protection against DC & AC short-circuit between all pins & ground with thermal overrange load dump voltage surge up to 40V & fortuitous open ground. No electrical insulation is required between the mounting tab & the heatsink but lead lengths should be as short as possible. TDA2003H has pins arranged for horizontal PCB mounting.NB The tab of the device is connected to Pin 3. Specifications Operating supply voltage DC 8 to 18 VMax. DC supply voltage 28 V Peak supply voltage 40V for 50ms Repetitive peak outputcurrent 3.5 A Non-repetitive peakoutput current 4.5 A Max. power dissipation 20W 90 C Frequency response 40 Hz to 15k Hz -3d B1W into 4 Omega Distortion 0.15 4.5W into 4 Omega 1k Hz Input impedance 150k Omega Open loop gain 80d B 1k Hz Closed loop gain 40d B 1k Hz Input noise 5micro V max.
