Part Number: LOG112 Other Parts Discussed in Thread: LOG114 I have a customer asking if he can connect the output of a single photodiode to two different LOG112 amps. I told him that this would not be a good idea as the current would not divide evenly…
Part Number: LOG112 I'm presenting this problem, not so much for troubleshooting our new design, but in hopes that someone may have seen this issue before.
We are using the LOG112 to measure the return current of a high voltage (3.5kV) power supply…
Part Number: LOG112 Hi Team,
The customer would like to select an op amp. The input signal is the current that is about hundreds of pA. The output voltage is the voltage.
I found LOG112 would meet the requirement.
Q1: If I recommend LOG112 to the customer…
Part Number: LOG112 Hi,
We have been using log112 for our sensor signal conditioning for the past three years. Recently smoking was observed in a few boards and the issue is the 10uF tantalum decoupling capacitor used. What will be a better alternative…
Part Number: LOG112 Other Parts Discussed in Thread: LOG114 , TL441 , , TL441-EP , LOG104 LOG112AIDR is Catalog (commercial) Part, we are looking for the automotive or Mill-Spec grade alternative part. Also Does TI offer any additional screening to increase…
Other Parts Discussed in Thread: LOG112 , LOG114 Page 9 of the LOG112 data sheet has a paragraph labeled "Voltage Inputs". In the paragraph, it states, "the dynamic range is limited to approximately three decades of input voltage etc."…
Other Parts Discussed in Thread: LOG112 Hi,
We have an application wherein Log112 is used.Supply for the same is +15V(pin6) and -15V(pin 9). To test the healthiness of circuit, we do the following tests.
Test 1
1.Connect equal resistance of 3.09M between…
Other Parts Discussed in Thread: LOG114 , LOG112 Hello,
I'm using the log 112 as a current sensor. I set I2 to 70.7nA as the reference current, and my input current I1 varies between 100pA and 50uA. I'm finding that I need a compensation capacitor Cc…
Other Parts Discussed in Thread: LOG112 Hello,
I designed a acquisition board for current measurement using the LOG112. The board reads 40 signal so it has 40 LOG112. In normal operation the input current are all near zero, and I notice that in this situation…
Other Parts Discussed in Thread: LOG112 , LOG114 Hi,
We are using LOG112 amplifier for one of our applications. We are planning to generate a reference current of around 14 mA using a resistance of 180 ohm with the inbuilt reference voltage Vref(2.5V).…
