Texas Instruments REF Series Current & Power Monitors & Regulators are available at Mouser Electronics. Mouser offers inventory, pricing, & datasheets for . The REF combines three circuit building-blocks on a single monolithic chip— two µA current sources and a current mirror. The sections are dielectrically. REF FEATURES. q COMPLETELY FLOATING: No Power Supply or Ground Connections q HIGH ACCURACY: ±% q LOW TEMPERATURE.

The subset of useful knowledge that is desired seems “a bit of a shame”.

They are ideally optimized for personal computer and CRT power supplies although they can be used in any number of off-line applications where energy efficiency is critical.

I’m using this rev200 conjunction with an INA Inst. Menu Search through millions of questions and answers User. Ask a new question Ask a new question Cancel.

When standard IAs can not deliver the required performance, consider this enhanced version.

Such knowledge is probably best kept from the masses. These and many other circuit techniques are shown in the Applications section of this Data Sheet. Independent 5V and 3. To make a temperature measurement system with a Doc. REF datasheet I tried searching Digikey for “current source” and ordering results by price.

This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet.

This is similar to the Datasheet section 8. ESD damage can range from subtle performance degradation to complete device failure. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Ultralow-power ma Low-dropout Linear Regulators. Jul 13, 5: Unlike typical boost circuits, the MAX output is completely disconnected from the input in shutdown. Hi Nurseda Baskent, I see no issue with this application. If you are trying to find another way to accomplish a technical task that is one thing, but just wanting a cheaper part is not a functional solution.

Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to rev200 its published specifications. The newly created question will be automatically linked to this question.


REF datasheet –

An overcurrent circuit breaker senses the voltage across the drain and source terminals of an external N-channel MOSFET with no need for a sense resistor. This is to read an RTD so the current must be low to prevent self-heating but accurate enough to calculate 0.

I figured I’d ask what I needed rather than ask several general questions to get to the same point.

The EV kit provides. Many thanks in advance! I’m using TI’s REF as a uA current source but need something cheaper with similar precision temperature stability, accuracy, etc. If this re2f00 no good then working up Dikgikey offerings in ascending price order or specing tightly and sorting by price shoud produce something suitable.

This integrated circuit can be damaged by ESD. I learned a lot from the short time spent looking at that requirement. Mentions Tags More Cancel. An internal high-side driver. Coupled with the fact. The advantages are a lower cost and reduced voltage and power loss in the switch path.
