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 I
2C-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
2C-bus without
additional hardware. Address, control and data to and from
the device are transferred serially via the two-line
bidirectional I
2C-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 I
2C-bus.
