Part Number: DAC53202 Hello, I intend to use DAC53202 with Internal Reference. As per my understanding the connection of VREF pin should be just a bypass cap when using Internal Reference.
Datasheet mentions to add a pull up to VDD when External Reference…
Hi Ishiwata-san,
I have finished my bench analysis with the DRV8881EVM.
The image below is driving a brushed-dc motor (12V, 6Ω) in Forward direction.
IN1 = HIGH
IN2 = PWM
AOUT1 = 12 V (Yellow), AVREF = 0.3 V (Blue), Motor Current (Green)
Operation…
Part Number: DRV8425 Other Parts Discussed in Thread: DRV8424 Hi team,
Limit of VREF are different DRV8424 and 5.
Does this mean that the rated current is different for 2.5A and 2.0A, but the internal circuitry of VREF is the same?
Also, if used beyond…
Part Number: TPS65400 Dear TI team,
Base on the PMIC TPS65400 datasheet, there have 4 Switching regulator(SW1,SW2,SW3,SW4), and the PMBUS command can sets the VREF(values from 0.6V to 1.87V).
Question:There have 4 VREFs, VREF1 for SW1. VREF2 for SW2,…
Part Number: TL432 Hi,
I have a POE supply design based on the evalboard . The TL432 is used in the feedback loop of the converter.

The design seemed fine until I noticed some drifting in the outpout voltage of the converter…
Part Number: LP-MSPM0G3507 Other Parts Discussed in Thread: MSPM0G3507
Regarding VREF of MSPM0G3507
A program with VREF enabled is written on the evaluation board and the output is checked with an oscilloscope. Noise appears approximately every 8 ms. I…
Part Number: LP-MSPM0L1306 Other Parts Discussed in Thread: SYSCONFIG Hi Team!
I'm trying to use an external reference of 2 V with the VREF module and ADC. I'm using example code adc12_single_conversion_vref_external as the starting point.
Software…
Part Number: ADS1298 Hello Team,
Thanks for all your helpful answers on this forum. I ask you again the same question as I have still not understood the how 300 mV is arrived at or calculated. ADS1298 Data Sheet Chapter 9.3.1.5.2 Input Differential Dynamic…
Hi Koyama-san,
The amount of error on the external 1.6V reference is really subject to the application's error allowed.
You can use the internal reference of the ADC and that has slightly more error.
Regards,
Rob
Part Number: BQ76PL536A-Q1 Hey TI team,
I am observing a rare issue in where CELL_UV/CELL_OV FAULT registers in this ASIC are asserted on bootup. I have some suspicion that there is an unstable Vref and was wondering if you could provide more details on…
