Qunqi 2Packs ADS1115 16Bit 4 Channel I2C IIC ADC Module Precised Analog-to-Digital Digital ADC Converter for Arduino Raspberry Pi

this video presents the ads-1115 which is a four-channel 16-bit analog to digital converter the ads-1115 also features a programmable gain amplifier and a programmable digital comparator a block diagram of the ads1115 is shown here where it could accept up to four analog inputs through pins analog input 0 to analog input 3. and inside the chip we have a multiplexer which can multiplex the four inputs the analog signal output from the multiplexer is then fed into a programmable gain amplifier which enables the ads-115 to accept different input ranges starting from plus or minus 256 millivolt up to plus a minus 6.144 volts the input analog signal is then fed into a 16-bit analog to digital converter and the 16-bit data is then transferred into the microcontroller using i-squared-c interfacing through pins serial data serial clock and the address pin the ads-1115 also has a programmable di
