Jade,
TLV2171 is sort of rail to rail input. The upper end does work although the performance is degraded. Like Kai said, it has more to do with the devices age than input range.

Hi Expert,
We are replacing commodity TL082 by using TLV2171 and meet an issue in min voltage detector circuit.
Could you please help to check whether…
Hi Yue,
The applied power supply voltages V+/V- are shared by the two amplifier sections internal to the TLV2171. That is not issue because each amplifier can be set up for an individual gain resulting in one output having an approximate 0 to +15 V…

Hi All,
I have a question about ADS8638. I understand that 1200pF is installed to suppress glitches, but the capacitance seems a little large…
Other Parts Discussed in Thread: TLV4171 , TIDA-01527 , TLV2171 Hi,
Is it possible to send me the actual Altium files (.SchDoc, .PcbDoc) for the reference design TIDA-01527, in order for me to use the products i purchased from your company even better…
Couldn't the ADS131 and C2000 be driven from the same filter path given a 1.5v common ? would it be best to add an OPA320 to drive the C2000 SAR ADC and connect the ADS131 to the output of the second part (B) TLV2171.
INA821 -> TLV2171 (A) -> TLV2171…

1.I design the board refer to the EVM TIDA-01371, and test single board without the output CAP of the negtive float_ldo very well.
2.But the load of this power board…
Hi Naveen,
Another device to consider which has better specs (other than bandwidth) than the TLV2171 is the TLV9302 . You will also have more output current headroom with the TLV9302 . The 1ku pricing online of the TLV9302 is $0.30 compared to $0.43…
Mike,
Are you sure the first amp is working well? For a robust design, the input pin voltages should be greater than 4V. I'm not sure you have that now.
The output is emitter follower as seen in section 8.2 "Functional block diagram" in the TL082…
