Part Number: INA1620EVM Hi!
I have bought the INA1620EVM. The documentation can be found here: https://www.ti.com/lit/ug/sbou205/sbou205.pdf
But there is an error - a contradiction - on page 5 - Section 3.2 - Cutoff Frequency:
When you look at the 2 formulas…
Part Number: INA1620EVM
1. R15=R20 is Not matched...
2. If we connect the IN- to GND,and Set R1=R7=1K ohm,R2=R6=2Kohm:
when using Equation (4), ,VRightChannelOutput = (1k/(2k+1k))*(1+2k/1k) * IN+ = 1* IN+
But using Equation (6) ,VRightChannelOutput = …
Part Number: INA1620EVM Hello,
I'm a bit confused. I replaced R1 & R7 with 1kohm resistors, and R2 & R6 with 10kohm resistors. I'm feeding the right channel audio input 1v. However I'm only getting 1.75v on the output, or 4.86db of gain. I thought with…
Hi Tamara,
That's not the question I was asking. But it was also very useful information so thank you. I'm pretty sure I'm doing things right by connecting my single ended source ground leg to both the ground and the inverting input pin. As my DAC is…
Now I have looked at the documentation for INA1620 and INA1651 (and INA1620EVM and INA1650EVM).
None of them really seem optimal. INA1620 only has 1 op amp in each channel instead of the 3 op amps of a 'real' instrumentation amplifier. And INA1651 (having…
