I2C 10 channel analogue to digital (atod) ic

I2C 10 Channel Analogue to Digital Converter
This IC has an standard 2 wire I2C interface. It is a 10 channel 10 bit converter with some additional features such as continuous (Autoscan) conversion and differential conversion.
By continually scanning and converting the A to D voltages it can take some of the pressure off of the host processor. Having an I2C interface makes the device very easy to use by issuing simple commands. The I2C works at up to 400kHz and to complete a full scan of the 10 channels only takes 450 uS. The full data sheet can be found at www.pin1.org in the Downloads section under I2C datasheets.
* Can continuously monitor all channels
* Operating voltage 2.0 to 5.5V
The IC is a standard narrow 20 pin IC package and the pin out's are as follows:
Pin Description1 +2.0V to 5V
11 SCK: this is the I2C clock
13 SDA: this is the I2c data
The reference voltage for the A to D conversion is set to VDD ( the +5V line) by default but pin 18 can be used and this can be selected by an I2C command. Here is a complete set of the I2C Commands:
Command AtoD Command Set1 Select channel
4 Fetch result of conversion
0x0A Read autoscan differential
0x55 TestCommand System Command Set0x90 Read EEPROM
0x92 Confirm Command Complete
0x99 Change Device Address Permanent
