Other Parts Discussed in Thread: DEM-OPA-SO-1A Hello TI engineers
I saw PCB for high speed amplifier DEM-OPA-SO-1A like a picture and I have 2 questions about this design.
1. Why top side has no ground plane?
2. Why ground plane at bottom side blank…
Hello Mohit,
Bread-boarding and socketing a high-speed part is a no-no. Please see section 11 of the datasheet for layout recommendations. An unpopulated evaluation module can be purchased from TI or local distributors for $5. Please see below. Using…
Hi, Thank you for your reply. They checked more detail of DEMB behavior on 8V output. Please refer to attached file. We got additional questions.

Hello Rakesh,
Unfortunately, we currently don't have an evaluation module/PCB that can accommodate the amplifier AND photodiode. We however have a generic PCB for the OPA659 in a SOT-23 (DBV) package. Please see attached. I would recommend going with…
Part Number: TPS54560B Other Parts Discussed in Thread: LM5085 , TPS54560 Hi,
Can TPS54560B replace LTC3864 ?
Based on LTC3864 with 100% Duty Cycle Capability, I check the TPS54560B SPEC as the below,
It means TPS54560B also can work in Vin=Vout…
Other Parts Discussed in Thread: OPA656 , DEM-OPA-SO-1A , LMH6629 Hi,
I am using OPA656 to measure the power spectral density of the gate current of 745 pA.
I am using a VI on labview for the noise spectral density measurements. Please find attached…
Low-Drop-Out Voltage Step-Down Converter .
My application is to take a 12V SLA Battery (12.5V to 14.7V) (DIODE-ORed with a 15V SMPS) and step it down to say 12.2V. I do have room to move the 12.5V upwards – but I want to see what drop-out voltage I…
Hi Carrot,
I was able to find this older app note which should still be relevant for this device. In addition to changing the boot strap capacitor, you can look at increasing the power consumption at VBUS.
Best Regards,

Hi MM,
I'm still familiarizing myself with this behavior. I will check what if any register settings can help prevent this. In the mean time, you can reference this app note for the TPS65200 but is still directly relevant to the BQ24157.
App Note…
