Hello BJ Han,
The LM7705 negative bias generator is produced by a different TI organization than by Precision Amplifiers so we are not as familiar with the product as our own. When I check the TI internal systems and search for an LM7705-Q1 automotive version I do not find any references to one. Therefore, it does not appear that there is an automotive version available. Additionally, I do not find an information indicating the existence of a combined LM7705/Op amp device even in the standard commercial product line-up.
