What is I2C ADC?
The I2C-ADC board is an I2C 12-bit, 8-CH Analog-to-Digital Converter module. The module can be configured as a Single-Ended Inputs Mode or Differential Inputs Mode. There are no external components required. Only two signal lines SDA and SCL plus supply voltage and ground are required to be connected.
What is the bit size of ADC?
ADC has a resolution of one part in 4,096, where 212 = 4,096. Thus, a 12-bit ADC with a maximum input of 10 VDC can resolve the measurement into 10 VDC/4096 = 0.00244 VDC = 2.44 mV. Similarly, for the same 0 to 10 VDC range, a 16-bit ADC resolution is 10/216 = 10/65,536 = 0.153 mV.
What is the resolution of 8 bit ADC and ADC?
Find out the resolution of 8 bit DAC/ADC? ∴ Resolution =28=256 possible output values.
What is 24-bit ADC?
The ADS1240 and ADS1241 are precision, wide dynamic range, delta-sigma, Analog-to-Digital (A/D) converters with 24-bit resolution operating from 2.7V to 5.25V power supplies. The delta-sigma A/D converter provides up to 24 bits of no missing code performance and effective resolution of 21 bits.
What is the resolution of an 8-bit ADC?
An ADC generates a digital output that’s proportional to the ratio of the input voltage to the input range. The resolution (Δ or least significant bit) is this range divided by the total number of possible steps. For example, an 8-bit ADC with a 2.048-V input range has a resolution of 8 mV (2.048 V/28 steps).
What is 8bit ADC?
An “8-bit” ADC returns a digital output code consisting of 8 bits. 2^8=256 possible code values. The ADC0808 also has an 8-input multiplexer, so this device is also “8-channel”. But what makes it an 8-bit ADC is the number of data output pins. Only one analog input channel is selected at any time.
Why is ADC 10-bit?
A 10-bit ADC has 210, or 1,024 possible output codes. So the resolution is 5V/1,024, or 4.88mV; a 12-bit ADC has a 1.22mV resolution for this same reference. ADCs come in various speeds, use different interfaces, and provide differing degrees of accuracy.
Is I2C a serial or parallel interface?
serial
I2C is the abbreviation for inter-integrated circuits. It is a synchronous, serial communication protocol which is intended to allow multiple slave digital ICs to communicate with one or more master chips.
What is a 10 bit ADC?
The ADC on the Arduino is a 10-bit ADC meaning it has the ability to detect 1,024 (2^10) discrete analog levels. Some microcontrollers have 8-bit ADCs (2^8 = 256 discrete levels) and some have 16-bit ADCs (2^16 = 65,536 discrete levels). The way an ADC works is fairly complex.
