- 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.
