Part Number: OPA4820 Other Parts Discussed in Thread: LMH6622 Tool/software: Hello,
I was wondering if there is any more information regarding thermal resistances for the following parts/packages. They have a theta_JA listed, but was hoping for a theta_JC…
Part Number: OPA4820 Hi Experts,
I use an LT1129 LDO to generate +4.5 V for the V+ rail of a TI OPA4820 op amp. When I power up the positive rail first and then the −4.5 V rail , the circuit operates normally. However, if I power up the −4.5 V rail…
Part Number: OPA4820 Hello,
Do we have data on the 2nd and 3rd Harmonics of the OPA4820 look like up to 60MHz? I only see up to 10MHz in the datasheet.
details of the signal and desired performance are below
- 60MHz differential sinewave
- Amplitude…
Part Number: OPA4354-Q1 Other Parts Discussed in Thread: OPA4820 Tool/software: Hi TEAM:
I am helping customer to seek an alternative to the OPA4354AIPWR to drive the MOSFET faster, as shown in the attached picture for MOS spec. After searching the…
Part Number: LMH32404 Other Parts Discussed in Thread: OPA4820 , LMH32401 , TLV3544 Tool/software: If using photodiodes as current sources, would the simplest way to AC-couple for ambient light filtering be via in-series capacitors prior to the input…
Hello Arik,
The OPA4820 should meet this requirement (210 MHz in G=+2). Is the customer looking for small-signal BW or large-signal BW? The LMH6722 is a current feedback amplifier and can also meet the BW in a gain of +2 requirements. Its noise is slightly…
Hi Jonathon,
I'm sorry your question missed our attention. The op amp you linked OPA4820 should work fine. For your application there are many amplifiers that would be suitable with only subtle differences in performance. You may want to consider…
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…
Other Parts Discussed in Thread: PGA113 , OPA4820 Hello Dear Friends and Masters.
im using PGA113 for first time in my project, i connected the output of one opamp (OPA4820) to PGA using one 100nf bypass Cap to CH1 .
i leaved the CH0/CAL pin floating…
