Datasheet A2TPMI TM
Thermopile with integrated signal processing circuit
FEATURES
Smart thermopile sensor with integrated
signal processing.
Can be adapted to your specific meas-
urement task.
Integrated, calibrated ambient tempera-
ture sensor.
Output signal ambient temperature com-
pensated.
Fast reaction time.
Different optics and IR filters available.
Digital serial interface for calibration and
adjustment purposes.
Analog frontend/backend, digital signal
processing.
E2PROM for configuration and data stor-
age.
Configurable comparator with high/low
signal for remote temperature threshold
control.
TO 39 6 pin housing.
APPLICATIONS
• Miniature remote non contact temperature
measurement (pyrometer).
• Temperature dependent switch for alarm or
thermostatic applications
• Residential, commercial, automotive, and in-
dustrial climate control.
• Household appliances featuring a remote tem-
perature control like microwave oven, toaster,
hair dryer.
• Temperature control in laser printers and copi-
ers.
• Automotive climate control.

Note 1: Extension to 120°C for limited periods of several minutes possible
Note 2: Limiting input pin current is only necessary for input voltages that exceed absolute maximum input voltage ratings
Note 3: Human body model, 1.5kW in series with 100pF. All pins rated per method 3015.7 of MIL-STD-883.
Static-sensitive device. Unused devices must be stored in conductive material. Protect devices from static discharge and static
fields. Stresses above those listed under “Absolute maximum ratings” may cause permanent damage to the device. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
Precautions should be taken to avoid reverse polarity of power supply. Reversed polarity of power supply results in a destroyed
unit.
Do not expose the sensors to aggressive detergents such as freon, trichlorethylen, etc. Optical windows (e.g. filter, lens) may be
cleaned with alcohol and cotton swab.
