TLV9002-Q1: typical test waveform

Josh,

See data sheet 9.2.1 TLV900x-Q1 Low-Side, Current Sensing Application & 9.2.2 Single-Supply Photodiode Amplifier

Hi Ron,

Thanks for your reply. There is no waveform captured by oscilloscope in datasheet.

I need your support on test waveform to show TLV9002-Q1 is an Amplifier rather than a buck converter or gate driver. Sine wave input is okay.

Thanks!

Josh

Configure it as a voltage follower (connect OUT to IN−, directly or with a resistor), apply any analog voltages to IN+ (directly or with a resistor), and check that the output voltage is the same.

To detect an opamp, two DC voltages (0.5 V or 4.5 V) are enough; these two voltages are chosen to rule out comparators (which would go fully to the rails) or opamps without rail-to-rail I/Os (which would not be able to go near one or two rails). But if you do this manually, you could just as well use a sine wave (0 V … 5 V peak-to-peak) at any supported frequency (up to 200 kHz; see figure 7-11).

Josh,

What has lead up to this question? It is in the top five of the "I can't believe they are asking for this moments" in my long career.

Hi Roland,

Please check the email with subject "EVT - test waveform for LM2903B/LM2904/TLV9002-Q1. Please reply with a waveform captured on oscilloscope following below requirement.

Requirement:

5V power supply, input & output signal.

Thanks!

Best,

Josh

Josh,

OK, but it gets the lowest priority. Complete by end of next week.

Hi Ron.

Thanks for great help!

Best,

Josh
