Hi, I have specified the TLV6742 in a new design, but it would be nice to have the shutdown feature. Do you know the estimated release date for this part?
Also, my design uses a 5V power supply. Could the shutdown pins be driven by a simple resistor divider from the 5V rail to form a basic under-voltage lockout feature on the op-amp?
Thanks.
Hi Ben,
It looks like the X2QFN/RUG package is knocking on the door. It's a 10-pin, 2mm by 1.5mm package. Here's the preview part online:
Judging by the internal status , I would guess it should be out in the next couple weeks. But, I'm not closely enough involved to know for sure. If this is urgent or really high priority for you, let me know and I can ask for a more concrete timeline.
As for your second question, I don't see any issues. The shutdown pins are high-impedance CMOS inputs. So, you don't have to drive current into the pins. My only concern would be setting the divider properly. The undefined region of operation for the pin is between V- + 1.1V and V- + 0.2V. In other words, say you set your resistor divider to output 1.2V (assuming single-supply). Then, you wouldn't know that the amp is going to turn off for sure until the shutdown pin falls to 0.2V. By this point, the supply voltage of the amp itself has probably already fallen quite a ways...something to consider.
Let me know if you have any follow up questions.
Regards,
Daniel
