General description

The PCA9691 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 64 PCA9691 devices connected to the I2C-bus without additional hardware. Address, control and data to and from the PCA9691 are transferred via the serial two-line bidirectional I2C-bus.

The functions of the PCA9691 include:

  • Analog input multiplexing
  • On-chip sample and hold
  • 8-bit Analog-to-Digital (A/D) conversion
  • 8-bit Digital-to-Analog (D/A) conversion

The maximum conversion rate is given by the maximum frequency of the I2C-bus.

Features

  • 8-bit successive approximation A/D conversion
  • Four analog inputs programmable as single-ended or differential inputs
  • 64 different addresses by three hardware address pins
  • 1 MHz Fast-mode Plus (Fm+) I2C-bus via serial input/output
  • Sampling rate given by I2C-bus frequency
  • Single supply voltage; operating from 2.5 V to 5.5 V
  • Low standby current
  • Analog voltage from VSS to VDD
  • Multiplying D/A Converter (DAC) with one analog output
  • On-chip sample and hold circuit
  • Auto-incremented channel selection
