Part Number: ADS8689 Other Parts Discussed in Thread: OPA320 , ADS8509 Tool/software: Hi,
I have a ADC design, based on the ADS8689IPW to measure a +/-800Vdc voltage connected to a 200:1 voltage divider. (We need to measure negative voltages to detect…
Hi Jonas,
Unfortunately the author of TIDA-01333 has left the company. Using a high value pullup to detect open wire is fine. For C44, compare the schematic to the text - C43 is the bypass cap on the OPA192. I believe that note is actually referring to…
Part Number: ADS8689 Tool/software: Hello,
My customer is investigating ADS8689. They understand AIN_P can work down to 0V(min), but it has -2mV(min) offset error even at Ta=25degC on all unipolar ranges, so they think ADS8689 may recognize as -2mV input…
Part Number: ADS8689 Our product uses ADS8689, which collects an analog signal that is a sine wave with a bias of 2.5V. AIN_P is connected to the analog signal, but we are not sure if AIN_GND can be connected to a bias voltage of 2.5V, and whether this…
Part Number: ADS8689 Hi Experts,
Good day.
Paragraph 7.4.2.1. RESET state "In order to exit any of the RESET states, the RST pin must be pulled high with CONVST/CS and SCLK held low. After a delay of tD_RST_POR or tD_RST_APP (see the Timing Requirements…
Part Number: ADS8689 Other Parts Discussed in Thread: ADS1118 , ADS1260 Hi
The customer has a problem with the ADS8689. If the input terminal needs to be reset to 0 ohm, the problem can be corrected.
ADS8689 PIN 7,8 SHORT
The software does not receive…
Part Number: ADS8689 Hello,
My customer has a question for ADS8689 2 nd -Order LPF.
The below is from the datasheet.
About -0.5dB can be seen for +-2.56V range during 10 ~ 1KHz range. So I guess that DC gain is also -0.5dB.
Is it really correct? They…
Part Number: ADS8689 Other Parts Discussed in Thread: ADS8681 Hello, My customer wants to evaluate ADS8689. But we don't have ADS8689EVM. Instead, we have ADS8681 EVM-PDK. Then they are asking me if this EVM can work with replacing ADS8681 by ADS8689…
