Section 12.2.4.2.3 as quoted:
12.2.4.2.3 VBUS Sense The VBUS voltage needs to be monitored for detection of the various valid signals (SESSEND, AVALID,BVALID, and SESSEND). The voltage…
Hi Dominik,
I'm assuming you will want to connect the single-ended voltage to the positive terminal input terminal, and connect a 7.5 V DC voltage to the negative input terminal. This will give you +/- 7.5 V of differential voltage swing. However…
Hey Quentin,
I don't think voltage stability is the issue here. I'm getting some noise, but in the mV not in the tenths of a volt.
Any clue on what would cause the lower channels to fail?
I never put any voltage above the specs on them. It's not…
Hey Jimmy,
I appreciate the schematic however I am unclear as to where the 1M resistors are?
Can you show where the 60V is getting divided down? is it at pins 5 and 12 of the relay?
Where are the 1M ohm resistors on the schematic?
What is the relay used…
Hello Daniel,
Regarding the PGA855EVM revision:
The only revision on the PGA855EVM involves the VOCM voltage divider connections through resistors R1 and R3.
Rev A connects the VOCM voltage divider resistors R1 and R3 to the LVDD+ and LVSS– (output-stage…
Part Number: TPS2595 Hello I would like to use a TPS259573DSG to set a custom 5.5V overvoltage lockout threshold (OVLO) with a 5 Volt input (normal, during fault it will be 7-8V which would damage the load thus why I am using an eFuse) How would I set a…
Hi Luke,
Luke Jones said: What is the reason to step down the 3.3V to 3V? If this is absolutely necessary, you would need a buffer to maintain this voltage at 3V.
Thank you,
The 3 volt reference is necessary as we are trying to maintain compatability with…
Part Number: TMS570LC4357 Hello guys, I have a question about the maximum input voltage of ADCpin. The specifications state that the maximum input voltage is 6.25V, but the input clamp current condition of ±10mA is "Ilk (Vi < 0 or Vi > VCCAD)".…
Part Number: BQ76952 Dear,
We are using BQ76952(5-volt Logic Level) and SPI flash(3.3-volt signal using voltage divider down logic level) on the same SPI bus. But getting the wrong data on Flash register read because if the BQ chip select is HIGH then…
Hey Leon,
What are the measured DC voltages measured at the inputs of the INA823. I see that the inverting terminal has a resistor divider from the supply but for the non-inverting terminal I am unable to tell what potential it is going to. I need to…
