产品描述

The LM74A is a temperature sensor, Delta-Sigma analog-to-digital converter with an SPI and MICROWIRE compatible interface in die form. The host can query the LM74A at any time to read temperature. A shutdown mode decreases power consumption to less than 10 µA. This mode is useful in systems where low average power consumption is critical.

This particular data sheet applies to the LM74 in die form. The LM74 is available in the 8-pin SOIC package as well as an 5-Bump DSBGA package please refer to LM74 data sheet for detailed specifictions pertaining to the packaged parts.

The LM74A has 12-bit plus sign temperature resolution (0.0625°C per LSB) while operating over a temperature range of −40°C to +150°C. The LM74A-5 MDA accuracy of ±3.5°C is specified over a temperature range of 0°C to +150°C.
