PCF8591P,112

The PCF8591P,112 is a 8-bit A/D and D/A Converter with a single-chip, single-supply low-power 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 bi-directional 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.

• Low standby current
• Serial input/output via I²C-bus
• I²C address selection by 3 hardware address pins
• Maximum sampling rate given by I²C-bus speed
• 4 Analog inputs configurable as single ended or differential inputs
• Auto-incremented channel selection
• Analog voltage range from VSS to VDD
• On-chip track and hold circuit
