LM26LV: Operating temperature range for not-Q1 models

user4884001

Part Number: LM26LV

The LM26LV data sheet suggests that all devices are designed for an operating range of -40°C..150°C (e.g. 6.4 Recommended Operating Conditions, 6.6 Electrical Characteristics).
On the contrary chapter 12- Mechanical, Packaging, and Orderable Information defines lower temperature limit for not-Q1 devices to 0°C. Which one is correct?

Hi,

The operating range for not Q1 devices is 0 -150°C.

The operating range for Q1 parts is -40 to 150°C.

Please follow the information seen from the orderable devices in chapter 12.

IMHO there is evidence, that in the ordering information something went wrong:
1. ) The old National Semiconductor data sheet for the LM26LV specified an operating range of -50°C..+150°C (for not Q1, because Q1 wasn't available at all) . Only the trip point range is limited to 0°C..+150°C.
2.) The actual TI data sheet also specifies in all other sections of the data sheet, even at page 1, (except in chapter 12) an operating range from -50°C to +150°C.
Maybe the trip point range was falsely transferred to ordering information?

Hi,

I see the concern here. I will look into this further, it is safe to say that the operating temperature is -50°C - 150°C operating range.

Hi Jalen,

thanks for digging a little bit deeper. We're still on hold if we can go on with this part and are curious about your (hopefully) soon answer.

Christian,

Thanks for having us look into this.

Both LM26LV and LM26LV-Q1 are -40 to 150°C.
