Tool/software: TINA-TI or Spice Models
Dear all,
Could you teach me the reason why the TINA-TI results is different from the actual value?
When I input 5V, the output voltage is 4.2V at TINA-TI.
The other hands, in fact, the actual output value is 4.8V.
Why does this difference occur?
Best regards,
Takao-san,
The TLV342 model is acting according to the section 3 description of the datasheet. This front page text says input common mode range is -0.2V to VCC - 0.8V, therefore the 4.2V limit in common mode is a early warning that common mode range is suspect.
I checked 3 devices (6 amplifiers) to see typical behavior at room temperature. Chart is VOUT vs. VIN.
Notice that each amplifier has a different response for input >4.7V (more obvious at >4.8V)
