Air-core gauge driver
These are pretty specialized products and are not very likely to be used by a broad range of customers so stock at disties my not be as good an indication of status as usual. For example, the CS8190EDWFR20G is listed as active by Onsemi and the Melexis part may be okay for availability, depending on your expectations. 

You will not be able to drive the air core movement directly from a micro- it requires two relatively high bipolar currents in quadrature, and typically with more compliance than the micro supply voltage. It's possible you could get it to work with PWM and two H-bridges rather than analog signals but that raises other issues such as EMI and you would have to evaluate the accuracy hit if you use voltage drive.
