Hi Andre
REFP pins needs to be decoupled to GND using 10uF capacitor. For sample schematic please refer ADS8861EVM-PDK.
Btw which reference device you are using to power 5V REF pin. TI has recently introduced REF6050 which can be good candidate to…
Part Number: ADS1258-EP Other Parts Discussed in Thread: INA326 , OPA388 , OPA228 , OPA320 , ADS1258 , REF6050 , REF6250 , REF6150 For a prototype project i need to Measure the environmental data like Temperature, Humidity, IR Radiation, etc. I am planning…
Hi Chris,
Looking at the electrical characteristics table of the ADS8860 (datasheet p3), the expected offset error of the ADS8860 (single-ended) device is typical ±1mV and ±4mV maximum. Since you are using the REF6250/LM4120 (5V reference), the LSB…

Hi Idan,
Sure, I'd be glad to help answer those questions!
First, synchronizing multiple ADCs requires that you use the synchronized clocks for all ADCs. Ideally, you'd want to have a single clock source routed to all ADCs (on the same card or on…
Shibin,
Placing a PTC fuse inside an op amp feedback is a reasonable approach. This document shows this approach to limit the amplifier output current: slides-protecting_low_voltage_adc_-_improved_solution.pdf on slide 2. You can also watch this in…
