DESCRIPTION

· The AT30TS74 is a highly accurate digital temperature sensor with a selectable resolution of 9 to 12 bits, offering ±1.0°C accuracy over the -20°C to +100°C range. It operates on a single supply voltage from 1.7V to 5.5V and measures temperatures from -55°C to +125°C. The device features a 2-wire I2C and SMBus™ compatible interface, supports SMBus timeout, alert, and alert response address (ARA), and allows up to eight devices on the same bus. It is available in various industry-standard green package options.
