Hi justin,
I remember an application where we had an unexplainable high offset voltage. Everything was tested and checked but we couldn't find the mistake. Then, suddenly the offset voltage dissapeared. What has happend? A sheet of paper was a covering…

Part Number: UC2846 Other Parts Discussed in Thread: OP27 Hello,
I am working on building a constant current DC power supply. It consists of two full H-bridge DC-DC converters feeding two HF transformers. The secondary side of HF transformers are connected…
I am having X1 DC input from OP27 opamp within 5 volts, X2 is ground for denominator......Z2 from another OP27 and Z1 is ground.....Y2 is connected to o/p as feedback and Y1 is ground.....Scale factor 4 and 3,5,9,13 are NC
Other Parts Discussed in Thread: OP27 , OPA637 , OPA27 Hi TI Engineers!
I had read an article about transipedance amplifier (TIA) that explains how to figure out the TIA's GBW as shown below.
My first question is :does this explaination useful in…
Tim and Fausto,
The OP27, OP37-type op amps (and their successors) have quite high input bias current and current noise. They are not well-suited to a transimpedance circuit with a 10M feedback resistor. A FET-input op amp is the correct choice in this…
Hi Chris,
Thank you for the valuable data.
The critical parameters for the replacement are:
Low noise, compatible with OP27
Low offset, compatible with OP27
Low susceptibility to RFI rectification
Availability of 2 op-amps in one pack is pref…

Would you please give me an idea about what's digital ground and analog ground short/common at one place only? Does the supply power ground to both analog and digital ground…
