Description
Unit ADC is an A/D converter with a built-in 16-bit self-calibrating analog-to-digital converter ADS1100. Through the I2C communication protocol, the ADS1100 can perform conversions at 8, 16, 32, or 128 samples per second. The on-chip programmable gain amplifier (PGA) provides up to 8x gain. For applications requiring high-resolution A/D conversion acquisition, Unit ADC is the perfect solution, with an I2C address of 0x48.
