Hi Otis,
Otis Chou said: Can OPA548T-1 supply voltage be used to V+=40V and V-=0V? When that situation what the max operating temperature is?
Yes, OPA548T-1 is able to operated with single supply rail, say 40Vdc and GND. It is within the recommended operating…
Part Number: OPA453 Hi Experts,
Our customer would like to ask if do we provide any recommended land pattern for given MPN? Or do we suggest desired drill size for the lead insertion with enough copper annular ring?
Because if they use any standard tool…
Part Number: OPA453 Hi Experts, May I ask for help? Our customer would like to confirm below for OPA453FA : " first: what to do with the FLAG (pin 7) when not using it? can it be left floating or do i need to connect it some how? btw. i miss the section…
Part Number: OPA453 Dear Sir/Madam
We are currently using OPA453 for our new analog design. And from OPA453 datasheet, the power supply voltage of absolute maximum rating and normal working conditions are same: 80Volts. From my understanding, most of…
Other Parts Discussed in Thread: OPA453 Hi,
I want to know the thermal resistance of OPA453.
The value I want to know is heat pad side, does anyone know the value?
Please help me with this question.
Best regards,
yasuhiro
Other Parts Discussed in Thread: OPA453 , OPA454 Aim: I have to design a circuit which can offset a digital signal (0 and 5V) by approx 70V DC. In other words, input is of 0 and 5 v and output should be 70V and 75 volt. The frequency of this signal is 10…
Maksim,
Sorry for the delay. Yes, your schematic shows a bridge output configuration. Note that this does not allow the load to be ground referenced. The load must "float" between the two amplifier outputs.
The output current of the OPA453 obviously…
Hello,
I'm not sure if a single stage amplifier can achieve all that you are looking for. You may have to cascade two stages (10x followed by 5x for 50x total) or more, and you may need output transistors to handle the voltage.
OPA552 can handle 70V…
Other Parts Discussed in Thread: OPA453 , LM5113 Hi,
I'm looking to drive GaN SW that has controls . On each control I need to have 0V or -40V (prefer -60V).
I need op amp that will act like comparator when I put "0" the comparator/opamp output will…
