Part Number: OPA4340 Other Parts Discussed in Thread: OPA340 , ADCS7476 Tool/software: OPA4340 voltage dip occurs when the power supply is supplied by the following op amp
Hello, I use OPA4340, OPA340 and ADCS7476 to design PT100 acquisition circuit…
Part Number: OPA4340 Tool/software: Hi Team,
my customer is using OPA4340 as below circuit, the vcc supply of OPA4340 is 5V, the output load is 0.6uF+660R, normally the output (VCC_3.3V_REF3) is 3.3V, but some time they get 1.65V output, could you…
Part Number: OPA4350 Other Parts Discussed in Thread: ADS1204 , OPA4192 , OPA4340 , OPA4197 , TINA-TI , OPA336 We are trying to determine if the OPA4340 would work as well as the OPA4350 in the circuit on page 14 of the ADS1204. Our input signals are…
Part Number: OPA4340 Other Parts Discussed in Thread: OPA340 , TINA-TI When calculating the output noise (rms) of the OPA4340 when used as a voltage buffer, I wanted to include voltage noise due to current noise (through the input resistors). But the…
Part Number: OPA4340 I am investigating an OPA4340 which failed.
Would someone please tell me when this chip was assembled and if it is affected by PCN# 20140409000 (i.e. which material was used for the bond wires)?
The specific part information is…
Other Parts Discussed in Thread: OPA4340 We were earlier using OPA4340 (CMOS fabricated) for Shock detection application, but now we want to go with another part, but unable to compare input impedance in terms of Ω || pF.
As most of the data sheet comes…
Onawa-san,
The LMV844 datasheet only provides output swing to the supply rails under specific 2 k and 10 k load conditions. We certainly expect with an even lighter load that the output will swing somewhat closer, but the datasheet doesn't make any…
Part Number: TIDA-01606 Other Parts Discussed in Thread: OPA4340 , Hi Manish,
As you mentioned in the design guide, the LEM senor phase A has a noise issue. However, I noticed that the LEM sensor Phase B also has the same problem. I noticed that in…
In case of current sensing, the OPA4340 is used over the OPA4350 in the voltage-sensing path due to the former's lower bandwidth. The lower bandwidth helps to reduce accidental amplification of switching noise that might be picked up by long traces in…
Hi Adam,
Thanks for your email id.
What are the voltage/current levels of the ADC inputs in your application?
Voltagle Level(on ADC input) = 1.2V
Current Level => Adc inputs are driven by OPA4340 OpAMP Buffer.
Regards
Marlin
