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…
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…
Hello Kotaro,
The input is a cascoded P-Channel CMOS input stage, based off the LMV751 low noise op-amp. Any further details are considered proprietary.
Bias currents are in the pA's. The bias currents are dominated by the ESD diode leakages (conventional…
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. …
to User473,
I searched all the op amp portfolio with the parametric search (precision, general purpose, and high-speed). There are 6 options with temperatures of 150C and above (see attached). The best match is the OPA211-HT (210C max). This is the…
