MAX6662 - 12-Bit + Sign Temperature Sensor

General Description

The MAX6662 is a 12-bit + sign temperature sensor combined with a programmable overtemperature alarm and a 3-wire (SPI™-compatible) serial interface in a single package.

It converts its die temperature into digital values using an internal analog-to-digital converter (ADC).

Key Features

  • a shutdown mode that saves power by disabling everything except the serial interface. The temperature sensor is available in an 8-pin SO package.
  • 12-Bit + Sign, 0.0625°C Resolution.
  • Accuracy ±1°C max (+30°C to +50°C) ±1.6°C max (0°C to +70°C) ±2.5°C max (-20°C to +85°C) ±2.5 typ (+150°C).
  • Extended Temperature Measurement Range -55°C to +150°C.
  • Low Average Supply Current, 125µA (typ).
  • Shutdown Mode to Minimize Power Consumption in Portable.

19-2121; Rev 0; 7/01 12-Bit + Sign Temperature Sensor with SPI-Compatible Serial Interface General Description The MAX6662 is a 12-bit + sign temperature sensor combined with a programmable overtemperature alarm and a 3-wire (SPI™-compatible) serial interface in a single package. It converts its die temperature into digital values using an internal analog-to-digital converter (ADC). The temperature data is stored in a temperature register as a 13-bit word, which allows 0.0625°C resolution. The temperature data is readable at any time through the serial interface. The operating temperature range is -55°C to +150°C. The MAX6662 provides two programmable watchdog interrupt outputs.
