• OPA340, OPA347 unpowered input to output leakage

  

  Sean Byrne

  Other Parts Discussed in Thread: OPA340 , OPA347 I'm looking to use an OPA340 or OPA347 as a simple comparator to monitor the voltage of the BR2032 battery. When the opamp is unpowered, if there any possibility of significant (nA) leakage from IN+ to…

  Hi Tony, Does your schematic now match what is shown in AN-31? If not, please provide the schematic. I put the OPA347 into the circuit shown in AN-31 into TINA-TI to simulate and I get the expected output in simulation. Have you tried simulating your…

  Hi D B17, Are you using the surface mount SOIC package or the through hole PDIP package? If you're using the PDIP package, here is a sort of all the parts with rail to rail input and output in a PDIP: www.ti.com/.../products.html I would recommend…

  Marek Lis

  Yes, that's correct. OPA2347 is a dual version of OPA347 single and OPA4347 is a quad-see below.

  I am using OPA347 rail to rail opamp with single supply and arduino pwm that can reach 0 and 5 volts. I think I have to experiment and see what happens in either configurations. I rememver before there was a post for interfacing LM35 with xtr117 with…

  Thomas Kuehl

  Hi Vishal, I searched for some electrically similar operational amplifiers to the OPA348 that are available in the PDIP package. I used the PDIP package availability and OPA348's 45 uA supply current as the leading criteria, supply voltage range and rail…

  John, I was able to measure the EMI-RR of the OPA347 this afternoon: I should note that the OPA347 is an unprotected device (no input EMI filter) and so its EMI rejection will be much lower than the OPA378.

  Hi Dean, Below you will find a microphone amplifier that I designed based on the OPA347. The OPA347 has a typical quiescent current of 20 uA and enough gain-bandwidth to easily support your 8 kHz circuit requirement. I set up the circuit up with a gain of…
