PCF8591P Datasheet | NXP Semiconductors

description The PCF8591 is a single-chip, single-supply 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. The functions of the device include analog input multiplexing, on-chip track and hold function, 8-bit analog-to-digital conversion and an 8-bit digital-to-analog conversion. The maximum conversion rate is given by the maximum speed of the I2C-bus. 2. Features and benefits - Single power supply - Operating supply voltage 2.5 V to 6.0 V - Low standby current - Serial input and output via I2C-bus - I2C address selection by 3 hardware address pins - Max sampling rate given by I2C-bus speed - 4 analog inputs configurable as single ended or differential inputs - Auto-incremented channel selection - Analog voltage range from VSS to VDD - On-chip track and hold circuit - 8-bit successive approximation A/D conversion - Multiplying DAC with one analog output. 3.
