If you don't need modern, there are still a few 10 V references in a metal can: LT1013, AD581.
Modern reference chips are more like 2.5 or 5 V and often not in a metal can any more. Two of the 5 V refs in series is an option.
The LTC6655 is good when it comes to noise and TC, but not that good when it comes to hysteresis and long term drift. So it depends on the requirements.
Hello,
the AD581 is only a bandgap reference. So it has about factor 5 more noise (with comparable current) and more ageing drift than a buried zener.
LT1031 (not 1013) and LT1021 (H-package) are metal can buried zener references.
When I measure a LTC6655 (5V) it usually has about the same noise than a buried zener 5V reference. (all in hermetically LS8-packages).
But the hysteresis is really bad for the LTC6655 even near room temperature.
The AD588BQ should play in the same game as AD587xQ. But if you do not need a dual voltage output the price is too high.
Ok I will be building the circuit attached, if I interpreted correctly @lars indications.
Depending on positive/negative T.C. of the AD587 you might have to put the thermistor either to ground or the output of the reference.
The resistor/trimmer in series to the 100K thermistor needs probably more than 20K.
The output voltage trimmer is around 200R to 1K depending if you take the default values of the other 2 resistors or if you carefully adapt them to the raw output voltage.
see also parts list of standard SVR reference:
http://www.gellerlabs.com/SVR%20M.htmlAdding a 7815 on the input can reduce the line regulation issues almost entirely.
I second this. I am usually using a LT1763 low noise regulator as low drop/low power pre regulator (thermally isolated from the reference). (Note: max 20V input)
Also might want to add a polarity reversal protection diode on the input (1n4001 or something).
of course yes if you do not have a voltage regulator with reverse polarity protection.
With best regards
