Part Number: OPA4830 Other Parts Discussed in Thread: TINA-TI Hello
Could you confirm if the OPA4830 SPICE model is working properly ?
I tried to import it in LTSpice - I'm used to do it - and just with a simple voltage follower I cannot get any…
Other Parts Discussed in Thread: OPA4830 We have a problem with operational Amplifier OPA4830, was used two configurations and when we use it like a buffer happened a strange response in output. We did a test with same conditions third and fourth figure…
Other Parts Discussed in Thread: OPA4830 , LM324 , TINA-TI , OPA830 Hello,
I bought operational amplifier OPA4830. TSSOP14 package with 4 operational amplifiers inside. Datasheet: here
1st - OP AMP I use as a summer
2nd - integrator
3rd - trigger…
Part Number: TLV170 Other Parts Discussed in Thread: OPA4830 Please read the attachment file. Could you shed a light for me to explain why TLV170 could not output a voltage while input current beyond 7mA in the circuit? But the circuit works while AD8044…
Hello Robert,
On Tina-TI, the input bias current for the LMH6559 is 3-10uA:
Our models are tested on both Tina-TI and PSpice. There has been a recent discussion where importing some models into LTSpice will show inaccurate currents. The thread link…
Hello Arik,
The OPA4820 and OPA4830 should meet the customers required specifications, however we do not have any populated boards. Can you please let us know if these parts will work for the customer as far as performance/ package/supplies go? In that…
Hello Gerald,
Yes, high speed amplifier group is the correct place for this type of application. Michael already gave really good suggestions. I will add a couple more below and here is an app note for NTSC composite video applications .
LMH6612…
Andrew, you probably should not be switching to a non-RR out device like the THS4211, here are your choices in RRout, higher slew rate VFA devices from TI or NSM, Be careful with those SSBW for the CMOS parts - those are false high numbers not even remotely…
Other Parts Discussed in Thread: OPA4820 , TL974 , OPA4830 I used the filterpro desktop to design a Bandpass filter. the parameters that i entered that deviated from the default values were: center freq = 125kHz Passband bandwidth = 10kHz Stopband bandwidth…
