Part Number: INA128-HT Hi,
I have some questions about 'Long-term stability' of electrical characteristics in INA128-HT datasheet.
What is the specific meaning of the long-term stability indicator in the electrical characteristics section of the datasheet…
Part Number: INA128 Tool/software: Hi,
I need some help on my design with INA 128. My circuit is simply an audio amplifier. It works pretty well, but I think that there is some high frequency noise at the output. Plese help me check the circuit, and…
Part Number: INA128 Tool/software: Hey,
I have a quick question relating to the ESD CDM rating of INA128U. The datasheet lists the CDM rating as ±50V. This seems really low, especially when compared to the ESD ratings of the parts in the device comparison…

The circuit is presented as a superior alternative to…
Part Number: INA128 Tool/software: for op amps, I keep finding PSRR has two different formulas. I'm having a hard time understanding why the equation is sometimes inverted.
PSRR = 10 log (ΔV supply 2 )/ ΔV io 2 )
and
PSRR=-20 log (ΔV io )/ ΔV supply…
Part Number: INA128 Tool/software: Dear Customer Service,
We ordered this product (INA128UA) from Texas Instrument many times. For some reason when we do the testing on our finished product it says it fails because of this components. When we do the…
Part Number: INA128 Good morning Sir
I would like to monitor a floating audio signal (the signal exists on the common part of 2 transformer) Because I want to use only 12VDC single supply, I made the midpoint Vref by using 2 resistors R2 and R3, buffered…
Part Number: INA128 Tool/software: Testing PSRR on the INA12XUA.
I am testing at dc,
for the circuit, we have in- tied to the output, and in+ tied to ground. I am measuring Vos between the vin- and vin+.
gain is set to 5V/V.
for the first measurement…
