PCF8591 8-bit A/D and D/A converter Rev. 7 27 June 2013 Product data sheet 1. General description The PCF8591 is a single-chip, single-supply low-power 8-bit CMOS data acquisition 2 device with four analog inputs, one analog output and a serial I C-bus interface. Three address pins A0, A1 and A2 are used for programming the hardware address, allowing 2 the use of up to eight devices connected to the I C-bus without additional hardware. Address, control and data to and from the device are transferred serially via the two-line 2 bidirectional I C-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 2 maximum conversion rate is given by the maximum speed of the I C-bus. 2. Features and benefits Single power supply Operating supply voltage 2.5 V to 6.0 V Low standby current 2 Serial input and output via I C-bus 2 I C address selection by 3 hardware address pins 2 Max sampling rate given by I C-bus speed 4 analog inputs configurable as single ended or differential inputs Auto-incremented channel selection Analog voltage range from V to V SS DD On-chip track and hold circuit 8-bit successive approximation A/D conversion Multiplying DAC with one analog output. 3.
