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 , 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…
Other Parts Discussed in Thread: PGA870 Hi,
In case monitoring the output while switching the gain, the following waveform was observed.
CH1：OUTPUT (However, this is not a PGA870 output. through a buffer and gain amplifier)
CH2：B5
CH3：B4…
Other Parts Discussed in Thread: PGA870 , TINA-TI While simulating the PGA870 with the supplied spice model in spice (spice3f5?) I get the follow error:
To few devs: f7a2e7d91a3c61eb88efe07d71e3bde5f3ef006d813376c6f627a228a81f4a556312313d5d1ca5ddece7a9ed1c5800d9915d8ed261cd9dfc1b42b13017f3a914…
Hi Jim Karki, is it possible to shift supply between +3.5V and -1.5V to perform a common-mode level near 1V for DC coupling without using a resistor network? In this case the mid-supply is now 1V, can I tie the undriven input to this value or to GND?…
Part Number: PGA870EVM Other Parts Discussed in Thread: PGA870 Tool/software: Hello,
TI provided me MATLAB code for the PGA870EVM attenuator, which is used to adjust the attenuation level of the attenuator in MATLAB. I was able to get this code working…
