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,…
Øyvin,
The best way to set the acquisition time to make sure that you get good settling is to do a simulation and look at the settling response. Even though the output of the op amp is connected to an RC the circuit is not a simple second order…
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…
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…
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…
Hi Meir,
I have some suggestion.

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 option…
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 source but…
Part Number: PGA281 Other Parts Discussed in Thread: ADS9110 , OPA2320 , THS4551 , OPA2625 , ADS8900B , OPA625 Is there a limitation of drivin SAR ADC directely ( kickback, settling , accuracy ).
In my understanding, a ADC-driver needs higher BW to handle…
