INDUSTRY'S MOST ACCURATE AND HIGHEST RESOLUTION SPI-COMPATIBLE TEMPERATURE SENSORS IN TINY 6-PIN SOT PACKAGES
SUNNYVALE, CA-September 7, 2001-Maxim Integrated Products introduces the MAX6630/MAX6631/MAX6632 local temperature sensors. Housed in tiny 6-pin SOT23 packages, they measure temperature accurately to ±1°C from 0°C to +70°C, ±1.6°C from –20°C to +85°C, ±2.3°C from –20°C to +100°C, and ±3.2°C from –40°C to +125°C. These devices are equipped with an internal 12-bit plus sign analog-to-digital converter that provides 0.0625°C resolution.
The MAX6630 performs a temperature conversion every 0.5s and the MAX6631 and MAX6632 perform a temperature conversion every 8s. Temperature data from the most recent completed conversion is available over the SPI-compatible bus interface and can be read at any time. Communication is carried out over the read-only SPI-compatible interface, which can reach speeds up to 5MHz.
The MAX6630/MAX6631/MAX6632 operate with a supply voltage between 3.0V and 5.5V. The low conversion rate of the MAX6631 and MAX6632 allows for a low supply current of just 32µA (typ). The MAX6630 has an average supply current of 200µA (typ). By pulling the CS pin low, all devices can be put into shutdown mode, consuming only 6µA (typ) of current. Prices start at $1.39 for the MAX6630 and $1.49 for the MAX6631/MAX6632 (2500-up, FOB USA).
