1 FEATURES
PCF8591
· 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. 2 APPLICATIONS 3 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.
· Closed loop control systems · Low power converter for remote data acquisition · Battery operated equipment · Acquisition of analog values in automotive, audio and TV applications. 4 ORDERING INFORMATION TYPE NUMBER PCF8591P PCF8591T
