  • ADC0820-N: VIN determination timing in WR-RD mode

    Resolved
    Part Number: ADC0820-N Hi, I am using ADC0820-N in WR-RD mode. I understand that a conversion is initiated at WR=L and latched at WR=H. From the following in the datasheet, I understood that the measured value of VIN (analog signal) is determined…

  • ADC0820-N: VIN loading effect

    Part Number: ADC0820-N Hi, I'm operating in a configuration where I've got a fixed pull-down resistor on VIN (4.7kohm), and then several different value pull-up resistors that are switched in/out to basically form a variable voltage divider. I'm…

  • ADC0820-N: oscillating outputs

    TI Thinks Resolved
    Part Number: ADC0820-N Hi, I'm trying to use the ADC0820 in an application without a microcontroller, so free-running. I'm not sure if I connected it properly to use it in that way; it seems to be working partially, but I'm getting oscillation on the…

  • ADC0820-N: Temperature range and accuracy - Datasheet error?

    Resolved
    Part Number: ADC0820-N The datasheet for the ADC0820 on page 2 says the ADC08020CCJ/CIWM are -40 to +85, and the ADB0820Bxxx are all 0-70. On page 3 the ADC0820C is given as +/-1 LSB and the ADC0820B as +/-0.5 LSB so it looks like you can't have 0.5LSB…
