  OPA378: OPA378 for high source resistance thermopile

  Part Number: OPA378 Hi, I am planning to use OPA378 for interfacing a thermopile that has 68kOhm series resistance. circuit attached. On the non-inverting input, i have the thermopile. 1. Due to the imbalance in the series resistors on inverting and...

  RE: OPA189: Using opamp to create a precision negative voltage reference. Can opamp drive decoupling caps?

  ...oh also let me know if there is a better TI opamp to use in the inverting opamp configuration. I'm not married to the OPA191. I like the OPA378 but my rails are +3.3V and -3V and it can't handle that wide of a supply range. The opamp needs...

  Slew rate Vs Gain

  Answer Suggested

  Hi, I'm doing some dynamic response calculations on a circuit and got the following doubt, OPA378 data sheet says that it's slew rate is 0.4 V/us for G=1. My problem is what is the slew rate figure if the gain is (G) 20? Thanks in advance...

  RE: TINA/Spice/OPA4277: Discrepancy between TINA and SPICE AC simulation

  Hi Domenico, As I observed, in the course of debug that the open loop gain/phase has itself not coming up correctly for OPA277 net-list in PSpice, I checked with recently developed op-amp models like OPA350/OPA378. The design is working fine with...
