MIKROE-3394 ADC 8 Click Mikroe MIKROE-3394 ADC 8 Click is a high-precision, low-power, 16-bit analog-to-digital converter (ADC). The Mikroe ADC 8 Click is based on the ADS1115 IC and can sample signals on four single-ended or two differential input channels. The ADS1115 can't use an external reference, so it incorporates a low-drift programmable voltage reference and the programmable gain amplifier (PGA). This allows for great flexibility in terms of the input signal level. The MIKROE-3394 samples signals from ±256mV up to 6.144V, allowing a very high precision for a wide range of input signals. This makes it an excellent choice for various instrumentation applications.
