Part Number: ADC081C027 Tool/software: Hello：
Now debug the ADC081C027 chip, connect an external 10K resistor to AIN and pull it to 3.3V for debugging:
1. Read the 0x00 register, the first two readings are 1, and the subsequent readings are both 0…
Part Number: ADC081C027 Other Parts Discussed in Thread: ADS122C04 , TLA2528 , ADC081C021 , ADS1119 Tool/software: Hi,
Is there an I2C based ADC that can support around 20 or more I2C addresses? I'm trying to implement a self test feature on a board…
Part Number: ADC081C027 Dear Texas Support,
The ADC081C027 has one address pin, which can be tied to VA, ground or left floating. The data sheet provides a nice simple diagram of the input, showing two 41.5 kΩ providing the mid-voltage when the pin…
Part Number: ADC081C027 My customer is trying to understand the exposure of a design mistake in which the supply for the ADC081C027 is 5V, but the I2C lines, with 4.75kΩ pullup resistors, are connected to 3.3V. Boards have been working, despite the fact…
Part Number: ADC081C027 We have installed at the field ~ 50K devices that use this chip.
We have an issue at the field with some of them ( 1%):
They need about 100 readings in order to give the correct result.
The first reading is about 1V higher than…

Hi,
In the datasheet of ADC081C027, we suggested 4.7uF tantalum capacitor with 0.1uF ceramic capacitor.
But tantalum capacitor is too larger and not widely used now.
Can we change it to 1uF or 4.7uF ceramic capacitor? …
Part Number: ADC081C027 Other Parts Discussed in Thread: TCA9535 I am trying to program the ADC081C027, but I am not able to get any results from any register, but the default settings. Even using i2cset and i2cget I am unable to set or change any values…
Part Number: ADC081C027 Tool/software: Linux Hello
I am trying to install the driver for the ADC081C027, but when compiling the code I ran into errors concerning err.h and a few other included files that I do not have on my linux machine. I then tried…
Va is your supply (which is also your reference voltage Min=2.7V max=5.5V). So, if you apply 3V at Va and have an 8-bit resolution, every step would be 3V/256 = 11.72mV (256 = 2^8 and the 8 comes from 8-bits resolution).
The very first step (from output…
Other Parts Discussed in Thread: ADC081C027 Hi
My customer is developing their system with ADC081C027. They found a spike voltage at Vin pin.
The spike appears at up-edge of CLK #9 of frame3 in "Figure 30. Typical Pointer Set Followed by Immediate…
