Part Number: OPA455 Other Parts Discussed in Thread: OPA596 Tool/software: Hi,
I need a low-cost programmable unidirectional constant current source able to provide 1mA – 30mA from a 60V power supply into a variable load.
I will also need a solution…
Part Number: OPA455 Tool/software: Hi TIer
Could you tell me about OPA455 if single negative power supply, without the en function, how the E/D and E/D_COM pins should be connected more suitable.
Is it not com to have negative power, then the E/D is…
Hello Sarath,
My initial recommendation would be to check out our new OPA891. The device meets your slew rate and output current needs, as well as having a high GBWP and higher supply rails.
If you have additional spec concerns or needs, I can provide…
Part Number: OPA455 Other Parts Discussed in Thread: OPA462 Hi,
On the OPA455 data sheet, the slew rate is given as 32V/us. but in the Design Procedure (Section 8.2.1.2), it is said to be only 6.5V/us. Can I assume that's a typo? I'm pretty clear…
Hi Saravan,
saravanakumar Dinakaran said: I replace the op-amp from LM1875 to LM2876 it should deliver the same output.
Kai's recommendation will work. As Kai pointed out, you should simulate the circuit before putting it together. Since the circuit is…
Part Number: OPA455 Other Parts Discussed in Thread: OPA593 , LM2876 Hi TI team,
I am using third party (Boost/SEPIC/Inverting Converter) converting +ve 60V to -ve 60V which provide output current 10mA. With this supply I am connecting OPA455 +Vs = 60V…
Part Number: OPA455 Other Parts Discussed in Thread: OPA445 , OPA593 , OPA462 Hi，
The customer has a new requirement that requires the voltage swing rate to be 40V/us and the OPA455 to be 32V /µs, but would like to know whether it can be used. Or…
Part Number: OPA455 Is the input current spec for OPA455 still valid in overdrive (saturation) mode? What is the maximum input current in saturation mode?
How long does it take to recover from saturation once input potentials normalize?
Part Number: OPA455 Other Parts Discussed in Thread: OPA462 Hi
Can OPA455 use below circuit to boost the output current and the target output is +/- 75V ?
