PCF8591T/2,512

The PCF8591T/2,512 is a 8-bit A/D and D/A Converter with a single-chip, single-supply low-power 8--bit CMOS data acquisition device with four analogue inputs, one analogue output and a serial I?C-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 I?C-bus without additional hardware. Address, control and data to and from the device are transferred serially via the two-line bi-directional I?C-bus. The functions of the device include analogue input multiplexing, on-chip track and hold function, 8-bit analogue-to-digital conversion and an 8--bit digital-to-analogue conversion. The maximum conversion rate is given by the maximum speed of the I?C-bus.
