Unit ADC v1.1
SKU:U013-V11
Description
Unit ADC v1.1 is a unit integrated with a 16-bit analog-to-digital converter, featuring the ADS1110 chip with an internal reference voltage (2.048V). It achieves high-precision conversion at rates of 15, 30, 60, or 240 samples per second via the I2C interface. The unit includes a programmable gain amplifier (PGA) with a maximum gain of 8x, enabling direct measurement of weak signals. The ADS1110 also comes with an internal reference voltage (2.048V), supporting high-resolution measurements. It is widely used in industrial process control, factory automation, portable instruments, and more.
