Hello Arun,
Thank you for trying out the suggested values. The reason is due to these capacitors attenuating the signal at 20Hz input due to the suggested AC coupling cap values. However, with a pulse rise time of <10ns, the bandwidth you would need…
Hello Sumeet,
For the second stage VGA/PGA, I would recommend either the LMH6518 or PGA870 which have a wide gain range that includes attenuation and a fully differential output to drive an ADC and reduce the common-mode error and distortion as you mentioned…
Part Number: PGA870 Other Parts Discussed in Thread: LMH6517 , PGA281 Hi,
I am current designing a data acquisition board for my research. I am planning on using the ADC AD7381 . However, I was having a hard time finding an appropriate PGA to go with…
Part Number: PGA870 Hi Ti Community
Is there a minimum frequency response for PGA870.
Can it be used in audio applications in the frequency range 100Hz to 3kHz.
If not are there any fully differential PGA or VGA that is suitable for audio applications…

Tool/software: TINA-TI or Spice Models
Hi, i have simulated PGA870 with ±2.5 split supply and rest of the connected capacitors are used by referring datasheet.
I want to excite the circuit…
Part Number: PGA870 Hi,
Can you please confirm if the following topology is fine, wherein I use a transformer based differential to single ended conversion stage as shown below, to use the converted output to drive a single ended buffer? Assume input…
Other Parts Discussed in Thread: PGA870 , LMH6553 , LMH6702 Dear support team
Our customer considers whether they add LMH6553 after PGA870.
This reason is the following - Get 14db gain (differential input, single-end output) - Limit 1V of output voltage …
Other Parts Discussed in Thread: PGA870 , LMV7239 , LMH6702 I am working with a team of engineers to design and build a time-domain reflectometer. We need to input a signal into the base of a bjt with a range of 0 to 5V. We want to use the PGA870 to control…
Hello, I'm FAE of distributor in Japan.
My customers ask me spec,but not in data sheet.
Now they already built system with No latch mode.
They think to modify mode and ask some questions.
Q1) In case no latch Mode, What value ns does it need to fix…
