    Thanks for your interesting and informative piece on the AD584 voltage references. I received mine from China this week, the cheapest one for £3.50 delivered.

    I was surprised to find the board had an LH version device as it was discontinued in 2012 yet mine is date marked 1640, and the 'test certificate' is dated 2015. LOL!

    I love all this chinese stuff, what a joy for curious electronics hobbyists...
