Part Number: INA190 Other Parts Discussed in Thread: INA186 , , THS3120 , INA193 Hello,
I would like to know what options may exist for the INA190Ax using the SOT23-8 package inside TI's current sense amp or instrumentation amp which would allow me to design…
Part Number: THS3120 Other Parts Discussed in Thread: TINA-TI Hi,
Need your advice to understand why I could not use the THS3120ID as Alternative to LM6181IMX-8 – It doesn’t work on my circuit
Please see below Schematic + Compare of the c…
Part Number: THS3120
The datasheet of THS3120 shows a PowerFET drive circuit, but it seems that this circuit is not correct. The output voltage of THS3120 is from Vs to -Vs, while the source voltage of P channel MOSFET is -Vs, the Vgs voltage…
Part Number: THS3120 Hi,
I recently built an analog buffer board using this IC. Please find attached the schematics. After I power up, I am observing that the op-amps are getting excessively heated up. I am observing this heating even when there is no…
I will ask around, but I have not yet found any data on my end characterizing the parts mentioned (THS3120 & THS3121).
If you have any other questions for me to look into, please continue asking away .
Other Parts Discussed in Thread: THS3120 I have THS3120 EVM. I measured the voltage gain in the lab and it was 2 , however I need the gain to be 10, Which resistor should I change to get the gain of 10?
The R4 on the board is 499, and R3 looks like 124ohm…
Part Number: THS3120 Other Parts Discussed in Thread: , THS6012 , OPA2673 Hi,
Is there a newer, higher-current amp you would recommend over THS3120? I am planning on designing a setup to test PSRR as described in the SLAA414 application note. The application…
Other Parts Discussed in Thread: THS3120 , OPA2673 I’m trying to use the THS3120 for a design but am concerned about high current pulses in my system on the output pin. The datasheet only specifies the continuous output current capability, which is…
extra two questions need you help to check:
1. customer to add 1V peak to peak AC signal to the input, but only 8.8mV measured show in the scope, do you know why? I saw the document use THS3120 for measurement, does it means we need to tool for PSRR testing…
Gentlemen, thanks for your input.
I have recommended to use either THS3091 or THS3120.
Of course the customer will have to take care of a proper layout to achieve the desired input capacitance!
