Part Number: LPV521 Hi,
We are facing a similar issue to the one mentioned in the related question ( https://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/234909/maintain-input-impedance-when-amplified-is-not-powered ), but with a twist…
Part Number: LPV521 Hey team,
Just wanted to run some simulations by you for a voltage controlled current sink design. I had one odd measurement that I was curious to get your thoughts on. Attached is the schematic and graph in question.
The red line…
Part Number: LPV521 Other Parts Discussed in Thread: TINA-TI , Tool/software: TINA-TI or Spice Models Hi all
Here I come with a question for the LPV521 TINA-TI Model:
Does this model reflect the Bias Current behavior over temperature ?
Part Number: LPV521 Hello Team,
I have questions about the following table in the datasheet.
[8.1.1 Driving Capacitive Load]
When CL=10nF, "RISO=13.3kΩ(min)"(@5V supply) is described. In the case of 2.8V supply, does the minimum value…
Other Parts Discussed in Thread: LPV521 , LPV542 Hi there,
I am considering using the LPV521 in op amp in a band-pass amplifier/filter design. The amplifier will have a low BW (0.1-20Hz). I want to know what is the maximum gain I can achieve at 20Hz using…
Could you update figure 31 and 32 of datasheet?
At Figure 31, Crossing x and y represent VS=1V and VOUT=0V respectively? and also step of Y equal to 1V?
At Figure 32, Crossing x and y represent VS=1V and VOUT=2V respectively? and also step of…
Other Parts Discussed in Thread: LPV521 , BQ24295 Hello,
I want to measure battery charging and discharging current using series small value resistor and LPV521.
Suggest circuit interface using LPV521 to measure charging and discharging current using single…
Other Parts Discussed in Thread: LPV521 Hi all,
I'm using a LPV521 nanopower opamp at Vcc=1.8V with its inputs slightly below the lower rail (about -25mV)
The datasheet specifies common mode input ranges 100mV beyond either rail for Vcc =3.3V and 5V…
Other Parts Discussed in Thread: MSP430F5438A , LPV521 Hello,
I have a question about LPC521 follower, we are using it with MSP430F5438A, the input is 3.8V and after a resistor divider, 1.9V feed to LPC521 voltage follower. and output to a analog input…
Thank you for pointing to the Application-Note.
Referring to our conversation earlier today let me summarize:
Crossover distortion is normally a problem encountered for OpAmps labelled as RRI (Rail…
