Part Number: INA149 Other Parts Discussed in Thread: AMC1350 , , INA146 , AMC3330 , TLV6001 , OPA391 , OPA396
I am working on an analog circuit to measure AC 220V 400Hz. I am using AMC1350 to convert +/-5V to +/-2V differential voltage signal…
Part Number: INA149 Other Parts Discussed in Thread: INA148 , , INA117 , TINA-TI My LTSpice sim of the models provided by TI for the INA149 do not work. I use the models for your INA148 and they work just fine, but not the INA149s.
The circuit runs 0-20uA…
Part Number: INA149 Other Parts Discussed in Thread: INA849 We are using the INA149 as the reader in a 4–20 mA loop. The INA is powered with a +15V and -15V supply. REFa and Refb are connected to ground, and the measurement resistor for the 4–20 mA loop…
Part Number: INA149 Other Parts Discussed in Thread: OPA186 , , INA143 , OPA333
I need to measure a battery voltage (between 0 and 5 V) as shown in the inputs to the INA149 on the top of the attached image. This battery negative or positive can…
Part Number: INA149 Other Parts Discussed in Thread: INA148 Hi Team,
Please take a look. Is it feasible to use INA149 to generate positive and negative sinusoidal currents with a maximum amplitude of 10mA? Is there any relevant information or practical…
Part Number: INA149 Hi, Staff
We are evaluating INA149.
Please confirm below. The circuit configuration of INA149 data sheet (SBOS579B) page13 Figi43 is evaluated.
What kind of voltage does Vout output when both the -IN and +IN input terminals are open…
Part Number: INA149 Other Parts Discussed in Thread: INA148 , INA146 Hi,
I have seen this part named INA149 belonging to differential amplifer, whose max common mode votlage can be up to 275V.
Could I learn the differences from current sense amplifier?…
You have two issues with your application:
1. The input voltage is not 2V (so the output cannot be 2V) because of the unbuffered resistive divider in front of the INA149 difference amplifier
2. The INA149 Vinp linear range is 1.5V above the negative…
Part Number: INA149 Hi,
I was looking for a single to differential amplifier with a fixed unity gain with supply range of 10V.
INA149 is unity gain but it is single ended.
so what do you recommend that is available in the market.
