The PCF8591 module is a monolithic integrated, low-power, 8-bit CMOS data acquisition module. The PCF8591 has four analog inputs, an analog output and a serial I2C bus interface. This module is equipped with a phototransistor (light dependent transistor), NTC (temperature dependent resistor) and trimming potentiometer, which are connected to the PCF8591 via 3 jumpers.Characteristics * single power supply * low power consumption in standby mode * serial input and output via I2C bus * max sampling rate is determined by the I2C bus speed * 4 analog inputs are programmable as unbalanced or differential inputs * automatic channel selection * analog voltage range from VSS to VDD * 8-bit successive approximate ADC * multiplier DAC (multiplying) with an analog output https://elecena.pl/product/27745163/whadda-ad-da-converter-module-pcf8591 2025-01-23 https://elecena.pl/product/27745163/whadda-ad-da-converter-module-pcf8591 2025-03-23 https://elecena.pl/product/27745163/whadda-ad-da-converter-module-pcf8591 2026-01-25 https://elecena.pl/product/27745163/whadda-ad-da-converter-module-pcf8591 2026-01-30
