Part Number: TIPD107 Other Parts Discussed in Thread: TLV333 , OPA333 , OPA391 , OPA191 Hi
My circuit uses the TIPD107 reference design to generate 0-5uA current from 0-5V. The modifications I have are inserting a buffer at the same node as my load…
Part Number: TIPD107 Other Parts Discussed in Thread: REF200 The TIPD107 datasheet suggests that it can supply current upto 5 uA.
However, our requirements is to supply 300uA from a voltage source. Can TI suggest any of their design which can be used…
Part Number: TIPD107 Other Parts Discussed in Thread: INA326 , I want to be able to sense a voltage signal from a photomultiplier tube (in Volts... nominally it would be around 1 V). The voltage signal itself is around 360 Hz. I would like to be able…
Part Number: TIPD107 Other Parts Discussed in Thread: XTR111 , TIPD102 , INA326 , INA826 , OPA188 , Dear Team,
The present circuit given by tamara works for 0 to 10V and 1uA to 1000uA, there is a change in the
The requirement is 0 to 1024uA current…
Hi Miguel,
Thanks for your post. I can help. It looks like you are referring to TIPD107: http://www.ti.com/lit/ug/slau507/slau507.pdf
What is your expected input range?
What is your desired output range?
This design is for 0-5V in, 0-5µA out…
Hello,
So we can see what circuit you've been using please share the circuit schematic for your existing design. Without knowing what circuit you're working with one option would be a circuit similar to the one shown in TIPD107 .
To meet your goals…
There are several circuits that use op amps and BJT or MOS pass devices to create current sources with high output impedance. Take a look at the following reference designs: TIPD101 , TIPD102 , TIPD107 and also the XTR110 and XTR111 integrated circuits…
Hello,
Thank you for the additional information and your patience as we worked through some technical difficulties.
I would also use a single 15V supply to power the INA. That would place the common-mode voltage of your bridge (assuming R1=R2=R3=R4…
Sainer,
I suspect your stability issues are more related to the feedback loop of the switching regulator as opposed to the op amp itself. In general, capacitive load or capacitance on the inverting feedback node causes stability issues. Also, the output…
