The AT30TS74 is a digital temperature sensor from Microchip Technology, Inc. that offers a temperature measurement range from -55¬8C to +125¬8C with a typical accuracy of ¬±1.0¬8C over the -20¬8C to +100¬8C range. It features a user-selectable resolution from 9 to 12 bits, allowing for flexibility in measurement precision. The device operates on a single supply voltage of 1.7V to 5.5V and includes a 2-wire I¬=C and SMBus compatible interface, supporting high-speed communication up to 3.4MHz. The AT30TS74 is designed with built-in programmable high and low temperature alarms, and it incorporates a shutdown mode to minimize power consumption, drawing only 1¬µA in this state. It is factory calibrated and requires no external components, making it suitable for various applications in communication, industrial, and instrumentation fields. The sensor is available in multiple compact package options, including SOIC, MSOP, DFN, and WLCSP, which enhances its adaptability for space-constrained designs.
Microchip's AT30TS74 temperature sensor is capable of measuring and converting temperatures from -55ºC to +125ºC to a digital word and provides a typical accuracy of +-1.0ºC over the operating temperature range of -20ºC to +100ºC. The device is factory calibrated and requires no external components to help provide a cost effective solution. To reduce current consumption and save power, the AT30TS74 features a shutdown mode which turns off all internal circuitry except for the internal power-on reset and serial interface circuits. In addition, the device features a power saving one-shot mode that allows the device to make a temperature measurement and update the temperature register and then return to shutdown mode. The AT30TS74 is based on the industry standard "LM75-type" compatible temperature sensor and is a precision temperature monitoring device designed for use in a variety of applications. The device combines a highly accurate digital temperature sensor with programmable high and low temperature alarms, user-selectable resolution up to 12 bits, and an I2C/SMBus compatible serial interface available in compact packages.
