PCF8591 General 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.

PCF8591 Features

· Single power supply
· Operating supply voltage 2.5 V to 6 V
· Low standby current
· Serial input/output via I2C-bus
· 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
· 8-bit successive approximation A/D conversion
· Multiplying DAC with one analog output.

PCF8591 Typical Application

· Closed loop control systems
· Low power converter for remote data acquisition
· Battery operated equipment
· Acquisition of analog values in automotive, audio and TV applications.
