Part Number: OPA363 Hi, I would like to know if the OPA363 will be able to drive a 50nF load? If it can drive it, what is the maximum capacitive load that it can drive? If no, are their any alternate, high current/capacitance drive opamps that we can use…
Part Number: OPA363 What is the difference between the OPA363AIDBV and the OPA363IDBV other than cost?
There is nothing in the data sheet that tells me what the "A" in the part number refers to.
Hi Napoleon,
Thanks for your schematic. Have you been able to measure the square wave output on the output of the OPA363? It looks like the voltage output from the DAC might not be high enough to enable the OPA363 via the enable pin. The OPA363 datasheet…
Part Number: OPA380 Other Parts Discussed in Thread: OPA363 , OPA365 , OPA810 , TLV9002 , OPA376 , ADS1115 Hello,
I have two questions.
I plan on using the OPA380 as a current-to-voltage converter for a thesis project. The current source is a photodiode that…
Part Number: PGA112 Other Parts Discussed in Thread: REF3230 , OPA2364 , TINA-TI , OPA364 , OPA363 I am intending to use the PGA112 amplifier to measure voltages with a wide dynamic range. Peak voltage to be measured is 60 V, scaled to < 3V with a 100k /…
Hi Ross,
I believe you forgot to upload your schematic, but there are many other sources of offset that you are not considering, such as that produced by bias current flowing through large impedances, CMRR, PSRR, etc. You may find this article useful…
Hello Emmanuel,
I wonder if you have a potential instability because of the time-constants involved and the OPA363 servo-amp is unable to get to a stable voltage on start-up. One thought I have is to have a 1K resistor to ground on the non-inverting…
Other Parts Discussed in Thread: THS4131 , ADS8422 , OPA320 , OPA336 , OPA340 , OPA344 , OPA363 Hi
in a new design i like to use the THS4131 to drive the ADS8422 very similiar to what the ADS8422 datasheet proposes for "Fully Differential Input driver..." in…
Ben,
Shutdown current of OPA357 for Vs=3.3V is around 250nA at 50C (see graph below).
Since you only specified RR swing requirement but no speed, I would suggest you to take a look at OPA341 (see graph below) as well as OPA363, OPA373 and OPA322.
