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: 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: OPA2836 Other Parts Discussed in Thread: LM7705
Dear TI Engineer： I am using the OPA2836 to amplify a signal (0V~0.04V) 77 times(7*11). To get an accurate 0V voltage, whether I had to offset the amplifier's supply voltage by several hundred…
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 James,
The VOCM of THP210 is an input for output common-mode voltage control, you should not tie it to the ground when THP210 is powered by a single 5V power supply, but you can tie it to the ground when the THP210 is powered by a dual power supply…
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…
Hello,
The OPA392 has a very good output swing and can get very close to the supply rail voltage, as you discovered in your testing.
The datasheet specifies the maximum output swing to be 20mV from the rail for a no load condition, and 35mV from the rail…
The simplest way is to derive the Vref is by using a resistive divider - no need for another supply. However, it must be buffered with U2 as shown below.
Other than that, you could also use LM7705 (a negative charge pump) to drive the Vref pin.
Hi Leon,
One of the issue is that you are using our 36V high voltage IA for 3.3V near minimum low IA operation (and using single supply rail). We have plenty low voltage IAs that will work for your application.

Hi Corry,
I assumed that you are looking for op amp level shift circuit. Enclosed is two references.
