This ripple almost always points to reference decoupling and analog supply integrity. I suggest to check the VDDA/VSSA cleanliness. Keep VDDA well-decoupled (local bulk pluse high-frequency caps) and avoid sharing high di/dt digital return paths with…

Part Number: LM5145DESIGN-CALC Other Parts Discussed in Thread: UCC21520 , LM5145
Hello, I'm using the PSpice Model of the LM5145 for simulation design, but I've found that the model only has 14 pins, while the actual device has 21 pins. How can I resolve…
This is a complex topic with many considerations. Some general advice I can give:
Layout your analog and digital connections for separate ground planes, but you can connect the digital and analog GND planes to get the best of both worlds (layout designed…
Part Number: BQ25638 Hi TI team,
I found the dual-input charger design in a TI application note. I noticed that with two chargers, only one SYS pin is active and both charger outputs are connected only at the BAT pin. I have the following questions:

Thank you for sharing the schematic.
From my understanding of the circuit the initial issue it that the input signal is bipolar where the ADS1119 is not designed to measure that signal. This is due to the analog input going below AGND. Please see Section…
