So, I'm happy to have gotten this delicious 1750'er last autumn sun matured
For anyone interested - DigiKey now is showing 197 pieces in stock this afternoon. Next shipment due 4/25 if you need 200.
Now's the tiime to start that Vref factory you've always dreamed about....or build that 144 unit reference parallel Vref board, all in the name of chasing low ppm
Good luck!
Mmm I have a spare board
maybe just one more and some Mr Pettis Resistors this time
I think in a few years volt-nutting became like those wines estimator and start to say ...
1745 is a bad week
1743 is good week excellent with noise but a little bit of drifty, temperature coefficient is the lowest registered ever.
The 1741 is the excellence: very low noise, good solderability and the lowest drift ... those references leaves a slight smell of cinnamon on second layer of the PCB and do not fear mitigated temperature changes. Keep at temperature of 40°C before using, but better served at 50°C.
The excessive raw TC of the 1754 er LTZ1000A (chinese seller) could be only tamed by opposite behavior of 1522ers econistors.
