Part Number: TL072
Other Parts Discussed in Thread: TINA-TI,

Tool/software: TINA-TI or Spice Models

Customer is simulating TL072 SPICE model for below circuit. (0V output)

sloj067.zip

But the result of supply current is about 14.1mA, is it bug?

(Datasheet P13 is described 1.4mA_typ)

Best regards,

Satoshi

    Hi Satoshi,

    Yes this seems to be a bug in the model. There is a resistor connected between positive and negative power supply pins with a value of 2.143kOhm (  Line 32: RP    3  4 21.43E3 ). It should have been 21.43kOhm to produce the right 1.4mA supply current for 30V (+/-15V) supply. Thank you for pointing it out. We will correct it and update the model on web.
