D a t a S h e e High-Slope, Low-Power, Analog Temperature Sensor in an SC70 Package General Description The MAX6612 is a low-power precision analog output temperature sensor in a tiny 5-pin SC70 package. The sensitivity of the output voltage to temperature is a high 19.53mV/°C. This sensitivity provides superior noise immunity. The voltage/temperature slope is chosen to provide convenient bit weights when the MAX6612 drives the input of an ADC with a 2.5.

19-2546; Rev 0; 7/02 w w w . D a t a S h e e High-Slope, Low-Power, Analog Temperature Sensor in an SC70 Package General Description The MAX6612 is a low-power precision analog output temperature sensor in a tiny 5-pin SC70 package. The sensitivity of the output voltage to temperature is a high 19.53mV/°C. This sensitivity provides superior noise immunity. The voltage/temperature slope is chosen to provide convenient bit weights when the MAX6612 drives the input of an ADC with a 2.5V or 5V reference. The MAX6612 provides an analog voltage output proportional to temperature. Accuracy is ±1.2°C (max) at +25°C, ±3.0 (max) from TA = 0°C to +70°C, and ±5.5°C (max) from TA = -10°C to +125°C. Useful measurements can be obtained at temperatures as high as +150°C. Self-heating effects are negligible due to the low current consumption of the part. Unlike many analog temperature sensors, the MAX6612 is stable with large capacitive loads. Any capacitive load greater than or equal to 1000pF yields stable operation, providing broad flexibility in board-level design. The operating temperature range varies with the supply voltage, with a higher supply voltage enabling a wider temperature range. The MAX6612 can be used over a range of -10°C to +125°C with a supply voltage of 3.3V or greater. For applications with a supply voltage of 2.4V, the MAX6612 can be used over a temperature range of -10°C to +70°C. o Optimized for Use with ADCs o High Temperature-to-Voltage Slope o Able to Drive High-Capacitive Loads o Operates Up to +150°C o Low Current Consumption (35µA max) o No Calibration Required o Space-Saving SC70 Package Features MAX6612 Ordering Information PART MAX6612MXK-T TEMP RANGE -55°C to +150°C PINPACKAGE 5 SC70-5 TOP MARK ADG Pin Configuration TOP VIEW A 1 5 B Applications Base Stations Industrial Equipment Home Appliances Battery Packs Medical Instruments Portable Equipment GPS Equipment GND 2 MAX6612 OUT 3 4 VCC SC70 Typical Application Circuit VSUPPLY RPU1 VCC CS OUT CLOAD AIN_ VDD SDA RPU2 MAX6612 GND CREF GND MAX1137 SCL ________________________________________________________________ Maxim Integrated Products 1 For pricing, delivery, and ordering information, please contact Maxim/Dallas Direct! at 1-888-629-4642, or visit Maxim’s website at www.maxim-ic.com. www.DataSheet4U.com High-Slope, Low-Power, Analog Temperature Sensor in an SC70 Package MAX6612 ABSOLUTE MAXIMUM RATINGS VCC to GND ..............................................................-0.3V to +6V OUT to GND..................................................-0.3V to VCC + 0.3V ESD Protection (Human Body)...........................................2000V Current into Any Pin ............................................................20mA Output Short-Circuit Duration.....................................Continuous Continuous Power Dissipation (TA = +70°C) 5-Pin SC70 (derate 3.1mW/°C above +70°C) ..............245mW Operating Temperature Range ..............
