19-2546; Rev 0; 7/02 High-Slope, Low-Power, Analog Temperature Sensor in an SC70 Package General Description Features The MAX6612 is a low-power precision analog output Optimized for Use with ADCs temperature sensor in a tiny 5-pin SC70 package. The High Temperature-to-Voltage Slope sensitivity of the output voltage to temperature is a high 19.53mV/°C. This sensitivity provides superior noise Able to Drive High-Capacitive Loads immunity. The voltage/temperature slope is chosen to Operates Up to +150°C provide convenient bit weights when the MAX6612 dri- ves the input of an ADC with a 2.5V or 5V reference. Low Current Consumption (35µA max) The MAX6612 provides an analog voltage output propor- No Calibration Required tional to temperature. Accuracy is ±1.2°C (max) a
