PCF8591P Datasheet 8-bit A/d And D/a Converter

Manufacturer: NXP Semiconductors

Overview: PCF8591 8-bit A/D and D/A converter Rev. 7 — 27 June 2013 Product data sheet 1.

This datasheet includes multiple variants, all published together in a single manufacturer document.

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.

Key Features

  • Single power supply.
  • Operating supply voltage 2.5 V to 6.0 V.
  • Low standby current.
  • Serial input and output via I2C-bus.
  • I2C address selection by 3 hardware address pins.
  • Max 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.
  • 8-bit successive approximation A/D conversion.
  • Multi.
