LMP2012QML-SP: Amplifiers forum

Anastasios Antoniou
Prodigy 40 points

Part Number: LMP2012QML-SP

Tool/software:

The part number provided above according to the detail specification document (5962-06206) is available in two variants:

1. 5962L0620601VZA, LMP2012WGL-QMLV
2. 5962L0620602VZA, LMP2012WGLL-QMLV

Device type 01 is claimed to be TID tolerant up to a 50krad at HDR test conditions.

Device type 02 is claimed to be TID tolerant up to a 50krad at LDR test conditions.

Q1: Does this classification of the part means that device type 02 cannot tolerate the HDR test conditions?

Or device type 02 was tested both in HDR and LDR and proved to be tolerant on both test conditions.

I understand that a device that is HDR does not mean that is also ELDRS free. Is the opposite valid? 

Q2: i.e. Is there any case that a device can be ELDRS free (under LDR conditions) but susceptible to HDR? 

Thank you.

    Hi Anastasios,

    I'm not too familiar with this radiation testing. Please give me some time to reach out to the relevant experts about your questions. I'll update this post once I have a response.

    Sorry for the delay on resolving this.  Philip has reached out to our radiation experts but unfortunately they are out of office until January 6.  Philip will continue to support at that time.

    Hi Anastasios,

    Our radiation expert got back to us with a response. Red are the questions, and black are the responses.

    Q1: Does this classification of the part means that device type 02 cannot tolerate the HDR test conditions?

    TID data collected per wafer level for this device. Type 02 device means TI guarantees all spec parameters up to 50Krad at LDR test conditions.

    Or device type 02 was tested both in HDR and LDR and proved to be tolerant on both test conditions.

    No. Type 02 tested only at LDR test conditions and no HDR data collected from the same wafer.

    I understand that a device that is HDR does not mean that is also ELDRS free. Is the opposite valid? 

    In general yes, but it requires ELDRS free characterization per TM 1019 section 3.13.1 to qualify ELDRS free part and claim the opposite is valid. 

    Q2: i.e. Is there any case that a device can be ELDRS free (under LDR conditions) but susceptible to HDR? 

    It depends on the device technology.  I can’t confirm above.
