Part Number: LMH6629 Other Parts Discussed in Thread: OPA855 Tool/software: Hi all
Can someone help me understand the SNR calculation in Table 1 of SNOA942?
The footnote reads: (5) SNR computed as ratio of minimum signal (10nA) to input referred spot…
Part Number: LMH6629 Other Parts Discussed in Thread: LMH34400 , LMH32401 , THVD8000 Tool/software: Dear Tech Experts,
I am working on Gate Access Application using IR Light as a Transmitter and Photodiode as a receiver.
I am able to send digital…
Part Number: LMH6629 Hi TI forums,
How can I find the output impedance of the LMH6629? I am having issues with it being unstable (set to a closed loop gain of 40). I'd like to try in the loop compensation, which needs an estimate of the output resistance…
Part Number: LMH6629 Other Parts Discussed in Thread: OPA855 , OPA858 Dear Specialists and TI users,
In past when implementing Photodiode amplification stage for VLC I usually used a transimpedance amplifier such LMH6629 and then use a high speed…
Part Number: LMH6629 Hello,
On page 26 the datasheet advises: "If bias current cancellation is not a requirement, then Rf || Rg does not need to equal Rseq. In this case, according to Equation 3, Rf || Rg should be as low as possible to minimize noise…
Part Number: LMH6629 Other Parts Discussed in Thread: TINA-TI Hello,
Can you please advise if the Pspice model covers linearity of the amp (HD2,HD3, IM3, etc)?
It is not mentioned specifically in the list of features covered by the model...
Does…
Part Number: LMH6629 Other Parts Discussed in Thread: OPA855 , OPA858 I’m trying to use LMH6629 for single-photon detection from a Hamamtsu S13360 MPPC .
The pulses of current from the MPPC are small and fast. I believe they’re in the 10µA range and…
Part Number: LMH6629 Hello Team,
Posting on behalf of my customer:
We are trying to replicate the conditions for the op-amp with a single 3.3V supply as detailed in section 6.6 of the datasheet but noticed the low frequency open loop gain was only…
Part Number: LMH6629 Hi,
The input bias current temperature drift for the LMH6629 is not specified in the datasheet (online or pdf Rev I) - can anyone supply me with nominal/worst case specs, or data from a measurement please?
Many thanks,
Nic
