Hi Sinngo, Yes the power-on sequence and I2C bus are related for proper read/writes. If the ramp doesn't occur correctly the device may hold the SDA pin low as shown in your image. Since you're able...

Yes, the ADC is AC coupled. The worst offset value I have manually measured is 38 LSB offset. I guess , that matches the datasheet data of +/-7mV. I am looking at the OFFSET_REMOVAL_START_MANUAL of...

Hi Vaishak, In LDMOS mode, the "turn off" value of the FETDRV pins will be 0V. You should set the DAC values to whatever you want the "Turn on" value to be. Code 0x000 would be 0V in LDMOS mode....

Hi ttd, The VOUT is limited by the VDD voltage, as this voltage is what powers the output buffer. If your VDD is 4.75V, that will be the max output voltage. The Absolute Max Ratings table is more of a...

Thanks for the information Mudit. The minimum gain of ADC1A and ADC1B is 4. With the internal 1.25V VREF, that means your full-scale input signal needs to be <=1.25V/4 = 0.3125V. In order to fit...
