Part Number: LMH6629 Other Parts Discussed in Thread: TINA-TI , , OPA725 , OPA2743 Hey everyone!
I need to build a first stage amplifier, a transimpedance amplifier , for a photodiode. The diode has a very small suface area, hence I expect a relatively low…
Part Number: DAC7821 Other Parts Discussed in Thread: OPA725 , OPA277 Hi Team, One of customer designed DAC7821 and OPA725 refer typical application in datasheet. They found abnormal singal waveform during the power on even if no input to DAC7821. They input…
Hello,
I looked in the Specs Scheets and:
I need DIP (Dual in Line Package) with 2.54mm spacings of the contacts. The mentioned OPA725 would fit the requirements, however, I would need a DIP Package, which doesnt seem to be available for the OPA725…
Other Parts Discussed in Thread: OPA725 , OPA322 , OPA140 , OPA350 , OPA365 I’m using an OPA140 in a transimpedance application. The circuit needs to run with a 5V supply voltage. The circuit (pc board) works fine with OPA322 and OPA725 amplifiers. However…
Hi Akerb,
regarding your op amp question:
Per the supply configuration of the ADS8342, I assume the op amp you use will have a V+=5V and V-=-5V. Similar to the schematic in the ADS datasheet an op amp such as the OPA725 would work.
thanks!

Other Parts Discussed in Thread: MSP430F4619 , OPA211 , OPA725 , OPA827 , OPA734 , OPA703 Hi everyone!
I need your help with the MSP430FG4619
Actually i want 0-10V for my application but MSP o/p is 3.6V so iam using here RRIO amplifier but MSP430F4619 has…
Not sure why you are concerned with wideband instrumentation op amp as OPA547 is only 1MHz UGBW. Answer some of the following questions and we can propose an optimum solution. 1) Input signal amplitude and frequency 2) Desired Iout/Vin scaling 3) All…
First and foremost get all of the failures back here for Failure Analysis in parallel with our applications discussion. Go back through wherever you purchased the OPA549s from to process the Failure analysis. Mention you have communicated with the factory…
1) You cannot ever leave the input floating. If the input source is to be connected and disconnected you need a pull-down resistor where the Vin is removed. What load can your Vin Drive? Leaving the input floating totally changes the feedback and thereby…
