Product Overview

The PCF8591T/2,518 is a single-chip, single supply low power 8-bit CMOS data acquisition device with four analogue inputs, one analogue 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 analogue input multiplexing, on-chip track and hold function, 8-bit analogue-to-digital conversion and an 8-bit digital-to-analogue conversion. The maximum conversion rate is given by the maximum speed of the I²C-bus.
  • Single power supply
  • 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 Analogue inputs configurable as single ended or differential inputs
  • Auto-incremented channel selection
  • Analogue voltage range from VSS to VDD
  • On-chip track and hold circuit
  • Multiplying DAC with one analogue output
