Part Number: OPA838 Tool/software: Hi,
Could you please confirm the OPA838 power-down operation?
The question is whether this is simply a reduction of supply current or an actual disable with output disconnect.
Is the output still driving while…
Part Number: OPA838 Other Parts Discussed in Thread: TINA-TI , , OPA836 Tool/software:
OPA838IDBV used with a 5V single supply. 5V confirmed at pin5 & 6. Vref is disconnected from any other circuitry.
A simple circuit here, but it doesn't work. 2…
Part Number: OPA838 Dear all,
In the datasheet of the OPA838 there are the following recommendations for PCB layout:
1.Signal routing must be direct and as short as possible into and out of the op amp.
2. The feedback path must be short and…
Part Number: OPA838 Dear all,
I want to choose an accurate vale for an isolation resistor for my OP-AMP (OPA838), based on the datasheet OPA838 is very sensitive to capacitive loads and for make the system robust to instability we need to add an isolation…
Part Number: OPA838 Other Parts Discussed in Thread: TINA-TI Tool/software: HI,
I am implementing a transimpedance amplifier based on the OPA838.
I am using a BPW34 and would like to detect and evaluate a signal of 1MHz. The approximate current flowing…
Part Number: OPA838 Dear All,
I have designed a transimpedance amplifier as follows:
I leaned that loading effect can be detrimental to OPA circuit and is very important to be considered. I want to consider and design the output circuit in my…
Part Number: OPA838 Other Parts Discussed in Thread: OPA837 , OPA856 , OPA383 Dear all,
I have used OPA838 to design an transimpedance amplifier. This design will be used as to convert the output current of an ultrasonic transducer to voltage, the…
Part Number: OPA838 Tool/software: Hi, I would like to know which is the best solution to reduce noise, interference, non linearity, better SNR to improve signal of the ultrasonic sensor. I should use one of this part number of the SECO Sensor: SC042…
Part Number: OPA838 Tool/software: Hi,
I am implementing a transimpedance amplifier based on the OPA838 and I am experiencing oscillation. The following circuit (figure 1) has been implemented based on the sensor specification and the Application and…
Part Number: OPA838 Tool/software:
I have basic questions about the following configuration of an Op-Amp, which is transimpedance amplifier , I would appreciate your help to help me understand this:
First question, considering that the…
