I have run simulation for the circuit below, when I use OPA350…
Part Number: DAC3164 Other Parts Discussed in Thread: OPA625 , , TINA-TI I'm looking at using a current source DAC (such as the DAC3164) feeding a voltage-feedback buffer amplifier (such as the OPA625).
The application calls for a unipolar output (0…
Part Number: OPA837 Other Parts Discussed in Thread: OPA625 , TIDA-01055 I was wondering about the common-mode input range of the OPA837 when used as a reference buffer for an ADC.
The TIDA-01055 compares the OPA625 with the OPA837 as a lower power…
Part Number: PGA281 Other Parts Discussed in Thread: ADS9110 , THS4551 , OPA625 Hello Team,
would 15k resistors on both inputs of the PGA281 influence the noise performance?
Typically chopping input does not interface good with high impedance…
Part Number: LMP91000 Other Parts Discussed in Thread: THS4551 , OPA625 , ADS8910B Hi,
I'm planning to feed the output to the LMP91000 in 3-Lead Amperometric Cell in Potentiostat Configuration into a differential AN+/- input of an A/D converter. Best…
Hi Erik,
You can use this method, but the bandwidth of the amplifier must be high to support the fast settling times for the input sampling capacitor.
For the ADS8900B converting at 1Msps, you will need an input amplifier bandwidth close to 22MHz…
So I went ahead and looked at the settling plot in the OPA2626, this is almost certainly a slew limited settling time, would be much faster if the input edge was slowed to stay out of slew limiting. Little history,
This is a dual, non-power control…
Part Number: ADS8910B Other Parts Discussed in Thread: OPA2625 , , OPA625 , THS4551 , ADS8329 , ADS9110 , OPA2328 , OPA862 , THP210 , OPA320 , THS4561 , LM7705 Hi
A quick question on the ADC input driver type for ADS8910B. In datasheet page 59, the…
Hello Oba-san,
Each ADS8861 needs its own reference driver buffer. You could use 10 REF60xx, but I would suggest using 1 REF50xx for a single system reference voltage, and then provide a buffer for each ADS8861.
For the reference buffer, if the DC…
Hello,
We are looking into this and will get back to you soon.
In the mean time, it looks like you might be hitting an output swing limitation from the negative rail. The OPA625 has a 110mV limit from the rail. Would you confirm what voltage the OPA625…
