Part Number: LM7705 Hi team,
My customer is considering to use LM7705 + OPAMP
Could you answer for the question below?
Is it ok to apply separate power supply for VDD of LM7705 and +V of OPAMP?
For example, apply +5V to VDD of LM7705, and +13V to +V and…
Part Number: LM7705 Hi team,
My customer is considering to use LM7705.
Could you answer for the question below?
Is there any possibility that the IC will not work by the wrong capacitance of the capacitor(C10)?
Could you tell me recommended capacity…
Hey Jim
The output close to negative rail gets better with a true rail to rail output device, like the OPA990. The LM321 had to have a unique architecture . Unfortunately we don't have a pin-to-pin option with rail to rail output. The TL343's swing from…
Part Number: OPA376 Other Parts Discussed in Thread: TLV376 , , LM7705 , OPA340 Hi Team,
customer has done some simulations with OPAx376 and TLVx376 in LTspice.
They noticed that the output does not go below 10mV for both devices.
Would you know what might…
Hello,
Sorry for swapping the direction of current flow, I thought the amplifier was sourcing current into the ADC.
Yes, in that case a load resistor will likely be the easiest way to sink this current and provide extra output swing to the amplifier…
Part Number: LM7705 Other Parts Discussed in Thread: LM27761 All,
When looking at section 6.6 of the data sheet regarding min and max for Vout, I would like to know if these numbers are already guard banded accounting for the 4mV typical ripple? If they…
Part Number: LM7705 Other Parts Discussed in Thread: LM27761 Hi team,
My customer is interested in the LM7705 for op-amp negative supply.
According to the d/s, CFLY and CRES influence to the magnitude of the Vout ripple.
Could you tell me the equation to…
Part Number: LM7705 Other Parts Discussed in Thread: TINA-TI , LM317 , Tool/software: TINA-TI or Spice Models I am Building a DC power board using LM317's and LM7705. I can't find the spice model for the 7705 nor is it in the library I downloaded to use…
Hi Abdul,
Abdul Choudhury said: Can this be setup to give an attenuation of 1.0667, input voltage range 0.2V to 4.8V (V Source) outputting 0.1875V to 4.5V.
If I play around the calculation, here is what I am able to get. I am not sure what does attenuation…
Part Number: LM7705 Other Parts Discussed in Thread: DAC7760 , , LM27761 In continue to DAC7760: required voltage on AVSS
We want to use DAC in 0-36V output range. So we need negative voltage source as low as possible to -0.5V. Because the output range…
