Other Parts Discussed in Thread: LMH6882 Hi all
I have a question about LMH6882 gain control.
LMH6882 is a double channels PGA .Tthere are two modes in LMH6882（Parallel mode and SPI mode）. I do not know how to control the gain while only one channel…
Other Parts Discussed in Thread: LMH6882 , ADS4142 , LMH6682 I have a situation I’d like to ask you about. In my application I have a differential amplifier (LMH6882) feeding an ADC (ADS4142). The ADC is in differential mode. The VCM from the ADC is fed…
Other Parts Discussed in Thread: LMH6882 Hello,
My customer has a question about LMH6882.
[Q]
Please tell me how to connect of NC pins.(#28, 31, 32, 33, 36)
I think NC means Not Connect.
But 0.1uF are connected to them in EVM.
(ex : #28=DC1B…
Other Parts Discussed in Thread: LMH6882 , LMH6881 Hello,
My customer has a question about LMH6882.
[Q]
LMH6882 is Dual Amplifier.
But they are not going to use one.
(I understand LMH6881 is Single Amplifier. They can use LMH6881.)
Please…
Other Parts Discussed in Thread: LMH6882 , LMH6881 Hi, We like to use LMH6882 as baseband amplifier. We need to split and combine various signal paths. LMH6882's datsheet does not describe input, output and coupling performance on shutdown. Is some description…
Other Parts Discussed in Thread: LMH6882 , THS4502 , TINA-TI Hi, We are currently debugging a new ADC-based design and we are using an LMH6882 variable gain amplifier to fine-tune the incoming analogue signal. However we are finding that the output amplitude…
Other Parts Discussed in Thread: LMH6882 , USB2ANY We are prototyping the LMH6882 programmable amplifier and are attempting to change the gain but without success so far. We are trying to determine if the commands we are sending to the device are not…
Other Parts Discussed in Thread: LMH6882 I have just implemented an FPGA SPI interface to an LMH6882 on an evaluation board. My first verification test was to read the register contents as listed in Table 5 of the datasheet. Most were as listed but the…
Hello Loren
Thank you for your response. Sorry I haven't gotten back to you sooner. We are going to try adding a fully differential amplifier (FDA) such as LMH655x ahead of the LMH6882 and adjusting the common mode offset so the incoming signal is centered…
Other Parts Discussed in Thread: LMH6882 , TINA-TI Hello,
I'm using the LMH6882 SPICE model that I downloaded from the product webpage. I'm using it in LT SPICE. I can't seem to get the variable attenuation feature to work. Seems no matter what bit…
