Part Number: OPA551 Hi all,
I am investigating the OPA551FAKTWT and am looking for the following parameters below. Note that I am not looking for the maximum allowable junction temperature, but for this intent and purpose I need to see what the operating…
Part Number: OPA551 Hi Team,
I need help clarifying the inquiry below:
Page 17 mentions the following:
But the layout example shows that pin 1, 4 and 5 is connected
I can connect pin 4 to v- as the main source but it is not clear to me how to connect…
Part Number: OPA551 Other Parts Discussed in Thread: OPA549 Hi Team,
I have questions about the OPA551 datasheet. In page 18, it says that for PDIP package, the thermal resistance is 100 C/W, And on page 4, it says that the thermal resistance for the…
Part Number: OPA551 Other Parts Discussed in Thread: OPA552 , OPA549-HIREL I would like to know if there is an alternative for the op amp with the complete reference: OPA551FAKTWTG3 to stand a low temperature to -55ºC.
The reference OPA551FAKTWTG3…
Part Number: OPA551 Other Parts Discussed in Thread: OPA552 , OPA454 , OPA2991 Hi,
The OPA551 and OPA552 are two high voltage amplifier but one is unity-gain stable and the second is optimized for gains of 5 or greater.
What's the difference between unity…
Part Number: OPA551 Other Parts Discussed in Thread: OPA552 Hi. I have finally hardware built the version of an Howland Current Pump discussed in other threads.
Here the simulation file from which I took as reference to build the PCB:
Improved HCP_OPA551_Noise…
Hi Kibria,
I see two issues:
There's a mistake in the input voltage divider. The way the relays K8 and K9 are wired allows only the very small input bias current of OPA551 of 20pA to flow across the relay contacts, but no signal current. Keep in mind…
Part Number: OPA551 Other Parts Discussed in Thread: OPA552 TI Customer Support,
You answer to this question referred me to Altium Designer. I do not have access to Altium designer at Triumph. I was expecting a graph of the D2PAK vs copper area like your…
Part Number: OPA551 Hi, TI Support Team
Please inquire about the flag pin processing method.
Is there any problem in operation even if the flag pin (8th) is directly connected to GND?
When connecting directly to GND, is there any possibility of any problem…
