Frequenz = 100K for now. later will be 400k Sorry i can not Change to LSF because my prototype PCB the foodprint may not fit. If there would be some comment in the datasheet that it don´t work with I2C then i would have used diffrent part. Testing…
Melbin,
My only questions/concerns with your schematics are regarding the components connected to the EN pin.
The 100k resistor between EN and GND should not be required as there is an internal 400k pull down resistor present on this pin when the EN…
Hi Venkatavel,
Can you short the ADC inputs together to a mid-supply voltage and see if you are getting the datasheet noise performance at various filter, data rate and gain settings? This will tell you if there is an issue with the ADC or if the noise…
Part Number: LM73606 Hi team,
I'm an FAE supporting some industrial customers in Japan.
Please let me ask you about LM73606EVM.
Switching node of LM73606 was fluctuated when falling as shown in below.
Is this normal operation for this device?
Operating…
Part Number: BQ25703A Other Parts Discussed in Thread: BQ24610 , BQ24773 I have some question about BQ25703A;
1- I am using 1 cell 18650 Li-Ion battery( max 4.2V) and my input voltage is 5V-21V. So, I will use it in buck mode every time. Is it possible…
Hi Issii-san,
For example, if you use a DCDC converter for 5V power supply, if DCDC frequency = 400k Hz, then on the output voltage may have 400kHz, <30mV ripple depending on your output cap/inductor.
If the DCDC loop is not stable or due to other…
Part Number: LP38798 Other Parts Discussed in Thread: TIDA-01371 , , LM317 , LMS8117A , LM1117 , TLV431 Hi,
I am trying to design a low noise, high voltage linear regulator. It is being used to clean up a switching boost converter operating at 400kHz. I've…
Jim,
1. There is a 400k internal pull-up resistor to Vcc at all DIN pins that could cause this to happen. For me to better understand the situation, is the 5V at Vcc disabled at the time you see 2.12V when O_COM1_DTR1# is pulled up to 3.3V?
2. Would the…
Part Number: TXB0102 Other Parts Discussed in Thread: CSD13201W10 , SN74LVC2T45 Hi,
When using TXB0102 to drive MOS, it was found the output voltage of TXB0102 B-Side can only achieve 2.5V, not the 5V which is the VCCB. But when disconnect the MOS, the…
