OR:  

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 and benefits

  • 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.

NXP Semiconductors' products are specifically designed and manufactured to be used within the electrical, thermal, mechanical and other parameters set forth in NXP Semiconductors' data sheets. Quality and reliability data provided by NXP Semiconductors, such as MTBF, MSL and FIT, is intended to be a non-binding estimate of product performance based upon diffusion process, history only. It does not imply that any performance levels reflected in such data can be met if the product is operated outside the conditions expressly stated in the latest published data sheet for a device or in your application.
