Part Number: OPA2140 Has the OPA2140AIDRGR been released? based on previously provided info, it was supposed to be released in Nov-2021. there is no info on this part, except a couple of forum messages. can you provide the part's status and availability…
Part Number: OPA2140 The datasheet of OPA2140 does not explain how to connect the Exposed Pad of DRG package (S-PWSON-N8). Should it be connected to the GND potential, -Vcc, or just left floating?
Part Number: OPA2140
I need OPA2140 dual amp in DRG package. I found POPA2140AIDRGR, however it is not RoHS part. The data sheet advises contact TI on this part. What is part's production status? Is it RoHS part?
Part Number: OPA2140 My customer wants to use OPA2140AIDGKR with baking condition 24hour 125C.
Is it acceptable baking condition ?

Part Number: OPA2140 Hello Team,
My Customer is using the OPA2140 as a positive amplifier for low noise DC source. They do not found any information about input current noise in the datasheet. They did some tests and found out that the noise depends dramatically…
Part Number: OPA2140 Other Parts Discussed in Thread: TEST , Hello，
Our customer used OPA2140 as 0~24mA current source, there is no problem during simulation, but actually, he met a question using PCB to test.
1) single 12V power supply, 0~2V input, and…
Part Number: OPA2140 Hello,
We have a design where the minimum consumption on both amplifier power supplies (+/-12V) is a key design driver.
- What is the minimum quiescent current per amplifier to be considered ? At room temperature and in the whole…
Part Number: OPA2140 Other Parts Discussed in Thread: OPA2192 Hello,
I have some questions regarding OPA2140 used to
- buffer a 5V precision voltage reference to increase the load current
- invert the same 5V precision voltage reference to create a -5V…
Part Number: OPA2140 Other Parts Discussed in Thread: OPA145 , , OPA2145 Hi,all
In order to save one supply, I plan to use the +5V and the -15V which are available,as the supply of opa2140/opa145. So i want to know whether there are some problems with this…
Part Number: OPA2140 Tool/software: WEBENCH® Design Tools Hi,
I'm using Filter Design Tool to design an active low-pass filter which is also the ADC driver. The gain should be 0.25 to accommodate ADC's input range. However, I found that the smallest allowable…
