Part Number: INA149 Other Parts Discussed in Thread: , INA148-Q1 Hi Team,
Do we have INA149 automotive degree device as customer previous used INA149 for OBC pre-research and they would to upgrade to automotive level but couldn't found it?
Best…
Part Number: INA149-EP Other Parts Discussed in Thread: INA149 , Hi, Good day. Our customer wants to know the details of what has been enhanced in the INA149-EP compared to INA149 aside from wider temperature range. This question arises because our customer…
Part Number: INA149 I have a 5VAC input signal that I’d like to bring in via a diff amp, to protect against ground noise. Downstream from the diff amp, the signal gets rectified by a single diode (only the positive part of the sine wave gets kept). It…
HI DJ,
It is also worth considering the INA149.
The device can withstand common-mode voltage range up to 300V during a fault.
The INA149 device will offer you gain of 1V/V. and higher common-mode rejection at 100dB. It offers you relatively low offset…
Part Number: INA149 Hello,
In INA149 datasheet, I understand that 200V voltage difference can occur between pin 3-pin 4.
For example, pin3 is at 200V with respect to my GND, pin2 is at 195V with respect to my GND and my negative supply is connected to…
Part Number: INA149 Other Parts Discussed in Thread: ISO124 , , OPA140 Hello,
I have found this technote about the bootstrapped Howland current source:
I would like to make a low-level (nanoamps level) current source that forces constant current through…
Part Number: INA149 Other Parts Discussed in Thread: INA159 I am using INA149 and have some questions about its operating limits.
I am using it with the following inputs : V+ = 5 V and V– = 0 V, REFA = REFB = 2.5 V
My question is what is the…
Part Number: INA149 Hi,
I didn't find any curve about output impedance in INA149 (-EP) datasheet.
Does the spice model is representative for a "typical +25°C", on frequency range [1 ; 1Meg]Hz?
Best regards,
Emilien
Part Number: INA149-EP The INA149-EP has an absolute max common mode rating of 500V for 10s. Can it take higher voltages for brief periods of time? Let's say 750V for 10ms? Assuming the 10s rating is a dissipation limit then shorter pulses could be possible…
Part Number: INA149-EP Team,
My customer needs some help figuring out whether a TI device can withstand a voltage transient.
I’m looking at the INA149-EP op-amp, and we have a transient of 750V common mode voltage at the op-amp inputs for less than 10…
