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 I
2C-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
2C-bus without additional
hardware. Address, control and data to and from the PCA9691 are transferred via the
serial two-line bidirectional I
2C-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
2C-bus.
