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 CMOS¹data 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.

2. 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 V_SSto V_DD

Multiplying Digital-to-Analog Converter (DAC) with one analog output

On-chip sample and hold circuit

Auto-incremented channel selection
