Part Number: PGA280 Hi, I was just wondering if inputting a 20Vpp waveform into this PGA with a +/- 15V supply could possibly be causing damage to it. I am seeing some issues with slew rate (chip is throwing 0x18 Input Clamp Active error) when inputting…
Part Number: OPA2320 Other Parts Discussed in Thread: ADS127L11 , , OPA2206 , PGA280 Hello TI,
I'm working on a signal chain that inputs into an ADS127L11 for measurement. The chain was designed and simulated specifically for low noise.
Unfortunately…
Part Number: PGA280 Hi
I have powered PGA280 with +/- 13 and connected both Vsop and DVDD to + 5 volt, Vson to ground.
Connecting Vocm to 2.5V and shorting input, 2 volt appears on output. Reading output while increasing Vocm from zero I noticed that…
Part Number: PGA280 Hi,
I would like you to cofirm about below.
* Which schottky diode should be selected ?
According to datasheet of PGA280, there is following description.
VSN is connected to the substrate; therefore, the voltage at VSON or DGND must…
Part Number: ADS8598H Other Parts Discussed in Thread: PGA280 , ADS131E08 , OPA192 Hi,
I'm considering using an 8 channel ADC such as the ADS8598H (+-10V). I also like the functionality (a good number of gains) offered by the PGA280 along with its robust…
Part Number: PGA280 Other Parts Discussed in Thread: TLV333 I need some informations about the noise of the PGA280. We are currently reading data with a 24bit ADC. The ADC samples @ 4 Khz.
We hasn't implemented a digital filter yet because we want to test…
Hi KB,
The PGA280 does have the SPI interface as well as an internal multiplexer. The PGA281 is essentially the same device, but using a digital interface and no multiplexer. I used the PGA281 model in the simulation as the AC and DC performance is functionally…
Hi John,
Do you have a plan to release updated datasheet?
I'd like to confirm the specifications of SPI timing on it.
Currently it's not updated from Sept 2009 version.
