  RE: Amplifiers with larger load capacitance

  Huang, A "large" capacitive load is a relative term - you need to be more specific. Are you talking about few nano or micro-farad? The only op amp I know that can directly drive several uF capacitive load is OPA4350 but it is 5V (or +/-2...

  RE: ADS1258 input circuitry & opamps

  Hi Hakan, Buffering the sensor output prior to the RC filter makes sense! ...If you weren't MUXing between 10 channels, you would be able to take advantage of the low-bandwidth digital SINC filter at a lower data rate to provide additional noise...

  RE: 28075 Control Card: Bad ADC performance - only 7 bits valid?

  Brett, thank you for the information. We will use the suggestions when we will design our own board. BTW, I also measured the ADC of the (old) 28377D R1.1 control card. It uses the same circuitry as the 28075 board, but with a LPM7709 OPA, also...

  RE: Help to make the better choice

  Hi Kevin Duke and Joseph thanks so much for your reply. the DAC must satisfy with this specifications: resolution = 16 bits. Digital Voltage = 3.3V. Analog output Voltaje = -10V to 10V. signal bandwidth = 0Hz - 5KHz. the input signal...

  Aliasing problem.

  Hi everybody !!! :) I have a problem with rebuilding the signal in the computer, the Aliasing, so I need to find where is wrong, please just tell, if I've got a sample rate of 2400 KSP/S, then, I can acquire a 1KHZ signal whitout the aliasing is...

  opa4350 ,differential iput ,sigle-end out

  input a sine signal to the circuit, the frenquncy and amplitude do not change. the output always changes at a low frequncy could you help to explain that? thanks a lot.

  RE: ADS1256 strange problems

  dear thank you for your reply as you mentioned for ads1256 relating to graph i did not find it like that how we can see the noise free bit simply shorting the two input pins of adc which is select for analog reading but what i had seen that on 2...

  Presence of offset in the output

  Dear All, I have designed an ultrasonic receiver using opa4350 IC. One part of it is used to implement a band pass filter with Center Frequency of 25k. OPA4350 is a rail to rail IC. But output of my circuit is restricted to 400mv-4V range when I am...

  RE: Quad Op Amp Driving Capacitive load and fast Saturation recovery time

  Wen, With the very limited information you provided about the required op amp specifications (other than capacitive load drive and overload recovery time), I would direct you to take a closer look at OPA4350 or OPA4353 - they can drive directly capacitive...
