Part Number: OPA355 Tool/software: Hi there, The power supply setting for OPA355 is ±1.8V. What should be the logic level for controlling the enable pin, I see that the low level is less than 0.8V, and the high level should be greater than 2V. When using…
Part Number: OPA355 Other Parts Discussed in Thread: TINA-TI , TLV2365 , TLV365 , THS4551 I want to design a 4th-order Bessel low-pass filter MFB Topology with a cutoff frequency of 2 MHz. Even though I enter 2 MHz as the target cutoff frequency, the…
Part Number: OPA355 Other Parts Discussed in Thread: TINA-TI , OPA838 , THS4551 I am planning to design front end for ADC .. with low noise
if fC of filter is 10MHz and Input signal frequency is 500KHz then
So intial stage is Non inverting amplifier…
Part Number: OPA355 HI team,
My customer use OPA355 to design as below circuit.
But due to AD5161 is a adjust resitance. might be parasitic capacitance of AD5161 to cause some delay here.
so do you have suggestion here? change OP solution or add…
Part Number: OPA355 Other Parts Discussed in Thread: TINA-TI , OPA863A , LMH6642 , OPA863 , , OPA814 , OPA817 Hi there, I have an application that requires this op amp with a rail-to-rail voltage of 6.0 Vdc min to 6.5 Vdc max. As I understand the datasheet…
Other Parts Discussed in Thread: OPA355 Hello this is seongmun kim nowaday, i am running to simulation about noise analysis. but example noise information in macro is not correct for analysis. can i share the inforamtion about noise component for OPA355…
Part Number: OPA355 Other Parts Discussed in Thread: OPA340 Dear expert,
My customer is evaluating OPA355 in a schematic as below, OPA355 is enabled:
Here are the parameters. The input current is 10nA~1mA, generated by the photodiode after receiving…
Part Number: OPA355 Hello,
Now I am considering non inverting amplifier circuit (gain 2) using OPA355. Layout example is shown in figure 40 on OPA355 data sheet. "Noninverting input terminated in 50ohm" is recommended on figure 40.
I would like to…
Part Number: OPA355 Hello,
I use OPA355 in an high impedance non-inverting input stage: at the inverting input, I have the feedback resistor Rf=200ohm, and a resistor to GND Rin=1k.
At the non-inverting input, I have a resistive divider of 637k to…
