Part Number: ADC121C021
I use two ADC121C021 for sensing temperature.
When I only connected pull down resistor to VIN of the chip, I2C communication is not problem. I2C operate normal.
However, when I connect temperature sensor and read the ADC…
Part Number: ADC121C021-Q1 Tool/software: Hi team,
When the supply voltage (Va) drops below its recommended operating range, should I drop the voltage down to 0V(or xxV)
before applying the voltage again?
Or will it recover automatically without…
Part Number: ADC121C021 Other Parts Discussed in Thread: TPS22917 We are using the ADC12C021 similar to that shown in "ADC121C021: Oddly sensitive to value of capacitor on VIN" but with the battery voltage taken directly from the "HALF_BATT" location…
Part Number: ADC121C021 Hello,
What is the variation in the readout of ADC121C021? (Variation of the ADC alone, excluding the analog input circuit)
For example, if the analog input value does not vary by even a few uV and the expected readout value…
Part Number: ADC121C021 We're bringing up a new design using the ADC121C021, and we're having difficulty communicating with it over I2C at 400 kHz, but 100 kHz is okay. The first thing I thought of was to check the bus waveforms, but they look okay, with…
Part Number: ADC121C021 Hi,
I am using a circuit that combines your TMUX1308QBQBRQ1 and ADC121C021QIMKX. Is it possible to eliminate the external capacitor on the VIN side of the ADC121C021 and substitute a capacitor on the input side of the TMUX…
Part Number: ADC121C021 Other Parts Discussed in Thread: , LM4120 Hi,
With reference to the reference design in ADC121C021EVM Booster Pack User’s Guide, I would like to confirm that the ADC121C021 will not have any issue without the 4.7uF tantalum…
Part Number: ADC121C021 An 8-channel MUX is connected to the input of the ADC121. The ADC is using auto mode and the MUX channels are switched every 1ms before reading out with SDA. I would like to ask about the disadvantages of increasing the sampling…
Part Number: ADC121C021-Q1 Other Parts Discussed in Thread: ADC121C021 Hello,
What is "Tconvert"? The device converts periodically in automatic conversion mode. The intaerval is determined by Tconvert. But I cannot find what or how long it is in the…
