Product 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.

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.

Applications

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