SunFounder AD DA Converter PCF8591 Sensor Module for Arduino and Raspberry Pi

Introduction About PCF8591 AD/DA Chip The PCF8591 is a single-chip, single-supply and low-power 8-bit CMOS data acquisition device with four analog inputs, one analog output and a serial I2C-bus interface. Three address pins A0, A1 and A2 are used for programming the hardware address, allowing the use of up to eight devices connected to the I2C-bus without additional hardware. Address, control and data to and from the device are transferred serially via the two-line bidirectional I2C-bus. Performance of PCF8591 Single supply, low standby current Address by 3 hardware address pins Sampling rate given by I2C-bus speed 4 analog inputs programmable as single-ended or differential inputs Auto-incremented channel selection Analog voltage range from VSS to VDD On-chip track and hold circuit Multiplying DAC with one analog output Application AD/DA converter Component List - 1 * AD/DA Converter PCF8591 module
