Hello,
We're looking for an op amp which meets these requirements:
The TLV379 does not seem to meet the no phase reversal condition, but is low in quiescent current.
Thanks very much, Keith
Hey Keith,
Thanks for reaching out! Since the TLV379 is rail-to-rail, it will not have phase reversal for input voltages that are within the supply rails. I ran a test to check if there is phase reversal which is shown below. However, is there a reason why you would need to exceed the common mode voltage range? We do not recommend exceeding recommended parameters.
I noticed that you mentioned the quiescent current for the TLV9001 (0.06mA) is too high. Just curious, what is the Iq cutoff for your design? I would recommend the TLV9041 which has a quiescent current of 0.01mA and has a better long term supply than the TLV379. Would this work for the customer? Or does it have to be as low as the TLV379 Iq (0.004mA)?
*For the TLV379*
Below is the input and output waveform where Yellow is the input and Blue is the output. The circuit was in a buffer configuration where V+ = 3 V, V– = –3 V, and a 10k load resistor. There was 6.8V peak to peak voltage applied to the input, so it was exceeding the common mode range, but still inside the absolute maximum of 7V.
Based on the waveform below, as expected for a RRIO device there is no phase reversal for the TLV379.
