The TW9910 is a multi-standard video decoder and encoder chip that is designed for
multimedia ApPLications. It uses the mixed-signal 1.8V CMOS technology to provide a low-
power integrated solution.
FEATURES
Unique 1-Wire interface requires only one port pin for communication
Multidrop capability simplifies distributed temperature sensing ApPLications
Requires no external components
Can be powered from data line. Power supply range is 3.0V to 5.5V
Zero standby power required
Measures temperatures from -55°C to +125°C. Fahrenheit equivalent is -67°F to +257°F
±0.5°C accuracy from -10°C to +85°C
Thermometer resolution is programmable from 9 to 12 bits
Converts 12-bit temperature to digital word in 750 ms (max.)
User-definable, nonvolatile temperature alarm settings
Alarm search command identifies and addresses devices whose temperature is outside of programmed limits (temperature
alarm condition)
ApPLications include thermostatic controls, industrial systems, consumer products,
thermometers, or any thermally sensitive system
