ADS1115 16-Bit 4 Channel ADC
The UNIT UT33D+ Digital Multimeter can be used for microcontrollers without an internal ADC or for high-resolution analog measurements. With the ADS1115 integrated circuit, it has the capability to perform 16-bit resolution measurements at a rate of 860 per second. The built-in amplifier allows low-level signals to be amplified by 16 times. It can operate with voltage ranging from 2V to 5V. This board uses I2C interface for communication and can be assigned 4 different addresses using soldered jumper wires. This allows for the use of up to 4 boards for a total of 16 analog input channels.
