Other Parts Discussed in Thread: LMV751 , TLV9051 Hi,
I am using LMV751 as an input buffer. Pin5 3.3V, pin 4 connected to pin1 output to an ADC, pin3 input from 0 to 3.0V, pin2 GND. When input voltage (pin3) is higher than 2.83V, the output is 3.3V suddenly…
Part Number: LMV762 Other Parts Discussed in Thread: LMV751 , ABS Hi Team,
My customer would like to know "Equivalent Input Structure" about LMV762. Could you share this?
Regards,

Thank you for the fast and precise answer,
my chain is composed of :
- IEPE source of current (two npn transistor connected to a 24V buck boost) delivering 4 mA .
-A resistor bridge wich play the role of an attenuator with a fixed value of 16.
- a LMV751…
Luc,
Your input signal is 200mV range and output range is 3.3V, therefore the gain will need to be 3.3V/200mV = +16.5
For a 1% error due to input offset error requires a Vio maximum of 200mV*1% = 2mV or less.
Low noise is also helpful for small input…
