According to <a href="http://synthdiy.com">synthdiy.com</a> Rohm did indeed make a similar chip, named the BA 3812. It is mono however. Info is here: <a href="http://www.synthdiy.com/show/showproduct.asp?id=497">http://www.synthdiy.com/show/showproduct.asp?id=497

<div style="direction: ltr;">Panasonic/Mitsubishi have made a series of stereo EQ chips for a while now. They made them in 5 band and 7 bad packages. They're intended for consumer electronics, but that didn't stop Yamaha from using thousands of them in their professional products, such as their EMX line of powered mixers. They work well, are quiet, relatively cheap, and have a low parts count requirement. I don't know if these are still in production, or if they've been superceded by newer chips:
