Part Number: OPA625 Other Parts Discussed in Thread: OPA863 , OPA810 Trying to use the BOM cross tool to match up to the ADA4807-1, it came back with only the OPA625 which looks about right AC wise, but
The ADA4807-1 is +/-5V capable, while the OPA625…
Hi,
the datasheet clearly says that the input voltage must no go below the negative supply voltage. But this would be the case in your circuit, if the input offset voltage results in a voltage at the -input of OPAmp which is slightly negative compared…
Part Number: OPA625 What would you recommend for this :-
I need a new opamp to act as a buffer before entering the ADC we use.
Need dual supply +/-5v and able to deal with its input being its rails. (Not able to stop the TIA feeding it from saturating…
Part Number: OPA625 Other Parts Discussed in Thread: ADS124S08 , OPA320 , OPA350 , OPA333 Dear Forum Members, I'm writing to you regarding a design problem: We'd like to use the ADS124S08 in one of our products (i.e. sensor signal conversion) and besides…
Part Number: TMS320F28379D Other Parts Discussed in Thread: OPA625 Hello,
can I connect single ended (0-3V) signal to the differential ADC Input by connecting this signal tu (+) input and GND (-) input without loosing dynamic range and 19-bit resolution…
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 typical application…
Other Parts Discussed in Thread: OPA625 , TINA-TI According to OPA625 datasheet the nominal input bias current in High-Drive mode is +2uA, and the input offset current is 20nA. While simulating the SPICE model of OPA625 in TINA-TI I've noticed that the input…
Other Parts Discussed in Thread: OPA625 Hello,
I'm trying to use OPA625 in a current meter design. At first stage, the input signal is passed through a voltage follower to lower the output impedance. Here is a circuit:
According to the datasheet,…
Marco -
Here perhaps its best to continue using the LMP91000 and your sensors as normal, while amplifying signal going to ADC.
For simplest implementation, an amp like the OPA625 coupled with an ADC like the ADS8860 and oversampling/averaging it or filtering…
