2013年12月5日 · Re: LT3092 Programmable current source « Reply #13 on: December 08, 2013, 04:44:00 pm » Just thought I'd chime in with a small piece: The LT3092 has a near-identical topology to the LT3080, which is a voltage regulator that is often discussed here.

The LT3081, LT8612, and LT3092 data sheets give com-plete descriptionsof the devices, operationand applications information. The data sheet must be read in conjunction with this demo manual for DC2132A. The LT3081ER is as-sembleda in 7-lead plastic DD ( R) package with a thermally enhanced VOUT tab and with θJA = 15ºC/W.

2018年8月28日 · Apologies for the slightly cryptic and erroneous initial title. >>> I assume you are asking about making some kind of negative LDO that has a ridiculously low noise floor and great RF PSRR ?

2017年11月9日 · The LT3092's output current in this configuration is simply Reference Voltage / Shunt resistor. So, neglecting the temperature increase of the 12.5 Ohm resistor we'd need, we could calculate the effect of the temperature variation now quite easily: 0.5 …

2019年4月5日 · The LT3092 is great and it works, but it's not really designed to work below 0.5 mA. Schematic of my setup is attached. What I'd like to do is put both coils in series and just drive a single current, that way the exact current is biasing both coils at the same time.

2015年9月6日 · lt3092? At 0.1 % accuracy you will need to trim it, but it's reasonably accurate OOB so the trim adjustment doesn't need to cover a lot of range. Logged

2020年4月14日 · EDIT: I tried to use two LT3092's in parallel. I was expecting to double the current, but the second one only adds 200 uA « Last Edit: August 26, 2020, 10:23:21 pm by raff5184 »

2013年7月6日 · Hi folks, some weeks ago I found some new product being released by Linear Technology - the LT3081. Basically it's the same like LT3080 but with more features: current control via an extra pin, current sense output and a pin to give a current equivalent to the die junction temperature.

2017年10月24日 · The LT3092 looked promising as well, except it doesn't come in a TO-220 package, and I need to be able to dissipate some fairly large amounts of heat (if LED strings are significantly shorter than the design maximum).

2020年3月31日 · I have settled on the MAX6350 for the voltage side... Super 0.02% accurate, right out of the box... But, I am not finding an equally great current reference... I mostly see the REF200, but it only has a 0.5% accuracy... The LT3092 is even less accurate... I was hoping for more... Suggestions? Please and thank you.
