Other Parts Discussed in Thread: LM6172

Are LM6172AMGWFQMLV or LM6172AMGWRLQV rated for space operations, specifically with respect to radiation tolerance?

    Hello Dragan,

    You can find this information here:

    https://www.ti.com/lit/pdf/snaa186

    From the linked document:

    "National Semiconductor has released an ELDRS-free version of the LM6172 (LM6172AMGWRLQV, 5962R9560403VXA) that is rated to 100 krad(Si). National also has a version of the LM6172 (LM6172AMGWFLQV, 5962F9560402VXA) that is rated to 300 krad(Si) at high dose rate. The ELDRS-free version is only being qualified 100 krad(Si) since it takes over 1 year to qualify a product to 300 krad(Si) at low dose rate. The ELDRS-free part was actually tested to 200 krad(Si) before the testing was stopped. The part passed up to 200 krad(Si) but the standard radiation levels in MIL-PRF-38535 are 100 and 300 krad(Si), with no interim level at 200 krad(Si). The testing through 200 krad(Si) is presented here."

    The LM6172AMGWFQMLV falls under parts rated to 300 krad(Si) at high dose rate.

    Best,
