  • RE: REF3430: Samples do not seem to function: zero or wrong output voltage

    Yes the output capacitor is necessary for functionality between out_f and GND. No need for an input cap but it is recommended to reduce transients. Is the cap on the breadboard from out_f to gnd or from Vin to gnd? There was a few major changes from…

  • DRV8301: Voltage Reference Selection for DRV8301 and INA240A2 - Optimal VREF Choice?

    Part Number: DRV8301 Other Parts Discussed in Thread: INA240 , REF3430 Hello, I'm designing a BLDC motor driver and need advice on selecting the appropriate voltage reference value. I'm planning to use a single REF3430QDBVRQ1 to supply VREF for my MCU…

  • TMS320F28P650SK: about the external adc voltage ref design

    TI Thinks Resolved
    Part Number: TMS320F28P650SK Other Parts Discussed in Thread: REF3430 Tool/software: Dear Forum Members, I am designing a system using the TMS320F28P650SK MCU with its internal 16-bit ADC. Currently, I plan to use the REF3430 (3.0V output) as the voltage…

  • TCA9800: TCA9800 B side powered down

    TI Thinks Resolved
    Part Number: TCA9800 Other Parts Discussed in Thread: REF3430 , See attached schematic. We are using the TCA9800 to interface an MSP430 running at 3.3V to an ADC121C02 running at 3.0 V. This 3.0V is coming from a REF3430. The 3.0V is also being used…

  • RE: TMS320F280039: ADC pin measurement daviation

    Hello Cedric, I'm saying 100nF is too much for the REF3430 to support. 2x100nF is even worse The total load cap cannot exceed 10uF per the REF3430 data sheet. Best regards, Ibukun
