PCA9691T - 8-bit A/D and D/A converter

Download the PCA9691T datasheet PDF. This datasheet also covers the PCA9691 variant, as both devices belong to the same 8-bit a/d and d/a converter family and are provided as variant models within a single manufacturer datasheet.

Description

The PCA9691 is a single chip, single supply, low power, 8-bit CMOS1 data acquisition device with four analog inputs, one analog output and a serial I2C-bus interface.

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 Digital-to-Analog Conve.

PCA9691 8-bit A/D and D/A converter Rev. 02 — 27 January 2010 Product data sheet 1. General description The PCA9691 is a single chip, single supply, low power, 8-bit CMOS1 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.
