Part Number: OPA551 Hello, Is it possible to use the OPA551 with a single power supply For example, V+=28Vdc and V-=0V or is a negative voltage required for correct operation for example -15Vdc? Thank you for your help.
Part Number: OPA551 hi,
The OPA551 amplification circuit is shown in the figure below, with an input frequency of 2.5KHz, a 3Vrms sinusoidal AC voltage, and an output load of 100R. OPA551 will produce a sizzling sound, while the DC input will not produce…
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…
Stefano,
The 8pF feedback cap together with R2 cancels zero created by input capacitance and R1 stabilizing the circuit - however, one may use a larger feedback cap resulting with a lower bandwidth. Having said that, I have previously not run AC simulation…
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…
