1. General description
The PCA9691 is a single chip, single supply, low power, 8-bit CMOS
1
data acquisition
device with four analog inputs, one analog output and a serial I
2
C-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 I
2
C-bus without additional
hardware. Address, control and data to and from the PCA9691 are transferred via the
serial two-line bidirectional I
2
C-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 I
2
C-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+) I
2
C-bus via serial input/output
Sampling rate given by I
2
C-bus frequency
Single supply voltage; operating from 2.5 V to 5.5 V
Low standby current
Analog voltage from V
SS
to V
DD
Multiplying Digital-to-Analog Converter (DAC) with one analog output
On-chip sample and hold circuit
Auto-incremented channel selection
