Chip manufacturers design chips for this market... what you want is different from what this market wants... economics are against you... | |

The difference with the drv134 is that the latter contains a cross-coupling scheme, making it possible to drive a single ended load without consuming to much power because of shorting out one of the outputs to ground. This is especially nice if the output is a TRS jack and the type of plug (TS / TRS) is unknown. | |
