Part Number: TPS60400 Other Parts Discussed in Thread: LM27761 , LM27762 , INA826 , LM2776 Hi All,
Customers are evaluating LTC1983-5. Since Cout was pre-biased to 0.4 V, it was not able to start up normally. They added Schottky diodes. Although this…

I am designing a power supply circuitry for the analog front end of my isolated data acquisition module…
Howard,
I think that configuration would work, but I would still like to see the final schematic. Would this be for some ratiometric measurement?
I would note that I did have some comments from my email earlier about the generation of the ±2.5V…
Since the LM27762 datasheet is in PREVIEW status all of the package details need to be appended to the datasheet manually by the technical writer. We get the basic mechanical drawing in, but sometimes we forget that some packages have two, or three, additional…
Hi,
There are no p2p alternatives unfortunately, but other charge pump inverters in our portfolio are: LM27761 (with integrated LDO) , LM27762 (with integrated LDO) and TPS60400/1/2/3.

Hi spanky,

Now I'm wondering if I could use a single 3.6v battery to power it on the +/-2.5v range. My loadcell reads push/pull, but I only care about tensile loads (which is why I gravitated towards the 0-5v range). Forgive me for my…
Hi Dino,
I have not been able to find a device that integrates a negative charge pump like the MAX44267. We do have negative charge pump ICs, such as the LM7705 or the LM27762, but nothing that integrates this with an op amp.
Hi Bob,
You are good! We are here to support our customers.
The dual supply voltage rails will be the best option, if it is difficult to have a known or fixed Vcm in your input signal. If you only have single supply rail available on a PCB, you may…
Hi Jacob,
The layout is important because of large switching currents and high switching frequency. A proper layout is more than a good design practice. It is something you must have if you want to have stable operation of the LM27762.
