Part Number: INA114 Other Parts Discussed in Thread: INA121 , INA828 Hi
I have an application here I get a voltage measurement to be done at pins of a resistor of 300K powered by a fixed current source
The voltage maximum will be 0 to 10V
I…
Hello Amarnath,
When R5 becomes 0 ohms the input voltage at Vin+ is set to 5V which violates the input common mode range. This is resulting in the output saturating to 2.01V in simulation. Based off a +/-5V supply and a gain of 2, the Vcm versus Vout…
Hello Dmitry,
I checked the assembly documentation for the INA114, it only specifies the the topside marking marking requirements. The topside image corresponds to the correct format. There aren't instructions for bottom side marking of the device in…
Part Number: INA114 We have had some internal failures (14 in last 6months)of TI INA114BP with Lot Codes: (49Z7INW, 42Z7IMW, 48Z788W). I am inquiring if anyone using this part has had any history of complaints for any failures of these lot codes for this…
Part Number: INA114 Other Parts Discussed in Thread: INA202 , INA190 Hi
I re-open this subject
The generator now delivers stable 29.56 ua
but il need to add a current monitor which will control max current about 1MA in case of problem with tue generator…
Part Number: INA114 Hi,
I have a bridge diff. signal and I want amplifier this signal with a Instrumentation Amplifier.
For that I use the INA 114.
the amplifier signal should be convert with a SAR ADC. The SAR ADC use a 3.3V power supply. The analog…
Part Number: INA114 Hello everyone,
We are trying to measure the output voltage of the Strain Guage using he INA114 precision Amplifier. The strain Guage is connected in the form of Wheastone bridge wih 330 ohm resistors (Strain Guage Rg = 350 ohms…

Hi there,
I need a low cost alternate to AD8220 INA of Analog Devices. So, I'm planning to use INA114 to amplify the input signal with gain around 20 while the…
Hi Marek,
Thanks for your reply. Would attaching a ground at node 11 solve the problem?
I need Vin- for INA114 however, would that just be connect Vin- to ground?
Thanks!
Hi Michelle,
This is related to not having a dc path to ground on your input when you run a transient sim. For a dc sim, the capacitors effectively look like open circuits and the input source does not factor in to the output voltage. I believe the…
