Hi,
Figure 1 is a block diagram of the device, while Fig 2 is the real schematic of the EVM itself. Sorry it confused you.
It is a mystery to me also why the gain would be anything but 100mV/A, soldering a pair of cables should not change the gain. Is…

HI Venkat,
Regarding the VOCM, this is a 500kΩ-500kΩ voltage divider to the Vclamp pins that can be solved using fundamental/basic circuit analysis. If you have the clamps set at ±12V, then the VOCM when left floating is biased at GND (0V)…
Part Number: INA253 I am measuring about 15 mv Peak to Peak of noise in the 50 Khz region on the output. This seems to be in the chips spec. However it is being used as a feedback signal and is driving some oscillation. Where is the best place to filter…
Part Number: INA253 I have an issue of parts failing.
I am using the INA253A2 on the low (ground) side of a voice coil. I provides the current feedback for the Class A amplifier powering the Voice coil. The power supply for the amplifier is +/-30 volts…
Part Number: INA253 Hi,
I am designing where I have to measure current and I'll be using INA253. In unidirectional mode the datasheet proposes connecting REF1 and REF2 to GND, IN+ to the current "input" and IN- to current "output" (or: IN+ to the power…
Part Number: INA253 Other Parts Discussed in Thread: INA181 , INA180 , INA301 , INA290 , INA280 Hi expert,
I post it under INA253 because I cannot find other new suitable parts.
My basic requirement can be described functionally as below, does TI have such…
Part Number: INA253 Other Parts Discussed in Thread: INA250 Hello,
We selected INA253 and INA250 for current measurements in a HIL test rack application.
Can I ask you have a look at the schematic and layout below and give a feedback why the old setup…
Part Number: INA253 HI
My customer has some test about the transient output over current.
the circuit is as below:
over current: 105.6A
duration:720us
times of repetition:50130
interval time: 2250s
the peak current is beyond the largest current of the…
Part Number: INA253-Q1 Other Parts Discussed in Thread: INA253 , INA240 In my application i am using 24V and 80mA solenoids and 6V and 1.8A solenoid .so can we use INA253-Q1 IC?if no, then can u suggest any IC which have integrated shunt or external shunt…
